Introduction to Object Orientation Encapsulation Inheritance Polymorphism Abstraction Classes & Objects Python

📘 Part 1: Introduction to Object Orientation

  • Object Orientation = A way of designing programs around objects (real-world things).

  • Each object has:

    • Properties (attributes/data) → e.g., a Car has color, model

    • Methods (functions/behavior) → e.g., a Car can start(), stop()

Why use Object Orientation?

  • Models the real world better

  • Easy to reuse and extend code

  • Easier maintenance

  • Saves development time


📘 Part 2: Main Principles of OOP

  1. Encapsulation → hiding details

    • Example: You just call tv.turnOn(), you don’t care how it works inside.

  2. Inheritance → child class gets features of parent class

    • Example: Dog and Cat inherit from Animal.

  3. Polymorphism → same function, different behavior

    • Example: draw() works differently for Circle and Square.

  4. Abstraction → show only important things, hide details

    • Example: A car’s steering wheel hides the complex engine mechanism.

  5. Classes & Objects

    • Class = blueprint (like a recipe)

    • Object = actual thing created from blueprint (like a cake baked from recipe)


📘 Part 3: Python Basics Refresher

✅ Data Structures

Structure Written With Ordered? Changeable? Allows Duplicates? Example
Tuple () Yes ❌ No ✅ Yes (1, 2, "Hi")
List [] Yes ✅ Yes ✅ Yes [1,2,2,3]
Set {} No ✅ Yes ❌ No {1,2,3}
Dictionary {key:val} Yes ✅ Yes Keys ❌ dupes, Values ✅ {"A":10, "B":20}

✅ Variables

  • Must start with a letter or _

  • Cannot start with number

  • Case-sensitive (Age ≠ age)

  • Use meaningful names (student_age ✔ vs x ✘)


✅ Operators

  • Arithmetic: + - * / % ** //

  • Comparison: == != > < >= <=

  • Logical: and, or, not

  • Assignment: =, +=, -=

  • Membership: in, not in

  • Identity: is, is not


✅ Indentation in Python

  • Python uses spaces instead of { }.

  • Example:

if age >= 18:
    print("Adult")
else:
    print("Child")

📘 Part 4: Control Flow

  1. Sequence → run line by line

  2. Selection (if/else) → decision-making

  3. Repetition (loops) → repeat tasks

    • for loop → repeat fixed times

    • while loop → repeat until condition false

    • break → exit loop early

    • continue → skip one loop step


📘 Part 5: Functions

  • A function = block of code that does something specific.

def greet(name):
    return "Hello " + name

print(greet("Faaz"))
  • Functions improve reusability and organization.


📘 Part 6: Sorting & Searching

  • Bubble Sort → repeatedly swap until sorted (slow for big data).

  • Selection Sort → pick smallest, put in front.

  • Insertion Sort → place each new item in correct place.

  • Merge & Quick Sort → faster, used in real life.


📘 Part 7: Advanced Math

  • Factorial5! = 5×4×3×2×1 = 120

  • Permutations (order matters) → number of ways to arrange items

  • Combinations (order doesn’t matter) → number of ways to choose items


📘 Part 8: OOP in Python

class Dog:
    def __init__(self, name):  # constructor
        self.name = name       # attribute

    def bark(self):            # method
        print(self.name + " says Woof!")

dog1 = Dog("Buddy")  # create object
dog1.bark()          # Output: Buddy says Woof!
  • self → refers to the object itself (must always be used inside class).

  • Method vs Function

    • Function → independent

    • Method → belongs to a class/object


📘 Part 9: Flowcharts & Problem Solving

  • Flowcharts help visualize logic.

  • Example: A game where user inputs a number, computer generates random number → compare → check win/loss.



🔹 Cohesion (togetherness inside a class/module)

  • Meaning: How strongly related the functions inside one class are.

  • High Cohesion = everything in the class is focused on one clear job.

  • Low Cohesion = class does many unrelated jobs → confusing & hard to maintain.

✅ Example:

# High Cohesion (Payment related only)
class PaymentProcessor:
    def validate_payment(self): pass
    def process_payment(self): pass
    def send_receipt(self): pass

This class only handles payment-related workhigh cohesion.

# Low Cohesion (Mixing many jobs)
class Utility:
    def send_email(self): pass
    def calculate_salary(self): pass
    def draw_graph(self): pass

Here, one class is trying to do too many different thingslow cohesion.


🔹 Coupling (connections between classes/modules)

  • Meaning: How much one class depends on another class.

  • Tightly Coupled = classes know too much about each other → hard to change one without breaking the other.

  • Loosely Coupled = classes depend only on essential information → flexible and easy to maintain.

✅ Example:

# Loose Coupling (better)
class PaymentProcessor:
    def process(self, payment_method):
        payment_method.pay()

class CreditCard:
    def pay(self): print("Paying with Credit Card")

class PayPal:
    def pay(self): print("Paying with PayPal")

processor = PaymentProcessor()
processor.process(PayPal())  # Can easily swap methods

Here, PaymentProcessor only needs to know that payment_method has a pay() function.
It doesn’t care how PayPal or CreditCard works inside → loosely coupled.

# Tight Coupling (bad)
class PaymentProcessor:
    def pay_with_creditcard(self): pass
    def pay_with_paypal(self): pass

If you add a new method (e.g., Bitcoin), you must modify the class.
This makes the system hard to extend → tightly coupled.


🔹 Rule of Thumb

👉 Good software should be Highly Cohesive + Loosely Coupled:

  • Each class does one job well (high cohesion).

  • Classes know only what they must about each other (loose coupling).

That’s how professional software is easier to read, test, reuse, and maintain.




🔹 What is Abstraction?

Abstraction = show only important details and hide the unnecessary ones.
👉 Example: When you drive a car, you just use the steering wheel & pedals.
You don’t see the engine’s wires or fuel injection system — that’s hidden.


🔹 Types of Abstraction in OOP

1. Classification Abstraction

  • Meaning: Grouping similar objects into classes.

  • Analogy: Labrador, Poodle, Bulldog → all grouped as Dog.

  • Focus: Looks at similarities.

class Dog:
    def __init__(self, breed):
        self.breed = breed

dog1 = Dog("Labrador")
dog2 = Dog("Poodle")

Here, Dog is a general class for all breeds.


2. Generalization Abstraction

  • Meaning: Creating parent-child relationships (inheritance).

  • Analogy: "Mammal" is a general class → Dog, Cat, Horse are children.

  • Focus: Top-down → from general → specific.

class Animal:   # Parent
    def breathe(self): print("Breathing")

class Dog(Animal):   # Child
    def bark(self): print("Woof!")

d = Dog()
d.breathe()  # Inherited
d.bark()

Here, Dog inherits general features of Animal.


3. Aggregation Abstraction (weak “has-a” relation)

  • Meaning: One object contains another, but parts can live independently.

  • Analogy: A Car has a Radio. The Radio can exist without the Car.

class Radio:
    def play(self): print("Playing music")

class Car:
    def __init__(self, radio):
        self.radio = radio   # "has-a" relation

my_radio = Radio()
my_car = Car(my_radio)
my_car.radio.play()

4. Composition Abstraction (strong “part-of” relation)

  • Meaning: Stronger form of aggregation → parts cannot exist independently.

  • Analogy: A House has Rooms. Rooms do not exist outside the house.

class Room:
    def __init__(self, name):
        self.name = name

class House:
    def __init__(self):
        self.rooms = [Room("Living"), Room("Bedroom")]

h = House()
for r in h.rooms:
    print(r.name)

Here, Room objects exist only because the House exists.


5. Behavioral Abstraction

  • Meaning: Hiding implementation details of methods, only showing what they do.

  • Analogy: You click “Print” → you don’t know if it’s laser/inkjet, but you get output.

  • Focus: Method signatures, not how they work inside.

class Printer:
    def print_document(self):   # behavior is abstract
        raise NotImplementedError("Subclasses must implement")

class LaserPrinter(Printer):
    def print_document(self):
        print("Printing with laser...")

class InkjetPrinter(Printer):
    def print_document(self):
        print("Printing with inkjet...")

p = InkjetPrinter()
p.print_document()

Here, print_document() hides details, but each printer implements it differently.


🔹 Summary

Type Focus Example
Classification Grouping similar objects Dogs → Dog class
Generalization Parent-child hierarchy Animal → Dog, Cat
Aggregation Weak "has-a" Car has a Radio
Composition Strong "part-of" House has Rooms
Behavioral Hide method details Printer with different implementations

.


🔹 Classification

  • Meaning: Grouping similar objects into classes based on common properties.

  • Approach: Bottom-Up → start from specific objects → group them.

  • Question it answers: “What category does this object belong to?”

✅ Example:

  • Labrador, Poodle, Bulldog → all grouped as Dog.

  • Cat, Tiger, Lion → all grouped as Cat family.

# Classification Example
class Dog:
    def __init__(self, breed):
        self.breed = breed

dog1 = Dog("Labrador")
dog2 = Dog("Poodle")
print(dog1.breed)   # Labrador

Here, classification means: we group similar objects → all are Dogs.


🔹 Generalization

  • Meaning: Create hierarchies where specific classes inherit from general ones.

  • Approach: Top-Down → start from general concept → create specialized ones.

  • Question it answers: “What is the more general concept that covers this?”

✅ Example:

  • “Dog”, “Cat”, “Horse” → all are generalized as Animal.

# Generalization Example
class Animal:  # General (parent)
    def breathe(self): print("Breathing")

class Dog(Animal):  # Specific (child)
    def bark(self): print("Woof!")

class Cat(Animal):  # Specific (child)
    def meow(self): print("Meow!")

d = Dog()
d.breathe()   # Inherited from Animal
d.bark()

Here, generalization means: we create a general Animal class → and let Dog & Cat inherit from it.


🔹 Key Differences (Side-by-Side)

Feature Classification Generalization
Definition Grouping similar objects into categories Building parent-child relationships
Direction Bottom-Up (from specific → category) Top-Down (from general → specialized)
Focus Similarities among objects Hierarchies & inheritance
Example Labrador + Poodle + Bulldog = Dog class Dog, Cat, Horse → inherit from Animal class
Question “What category is this object in?” “What general concept does this belong to?”

🔹 Real-Life Analogy

  • Classification:

    • You look at fruits → Apple, Banana, Orange → group them as Fruits.

  • Generalization:

    • You start with “Plant” → then generalize into “Fruit” and “Vegetable”.


In short:

  • Classification organizes objects into groups.

  • Generalization creates parent-child hierarchies among those groups.

Q12: What is Polymorphism?
A12: Same method name, different behavior depending on object.

Q13: Python Example of Polymorphism?
A13:

class Dog:
    def speak(self): print("Woof!")
class Cat:
    def speak(self): print("Meow!")
for animal in [Dog(), Cat()]:
    animal.speak()

🔹 Cohesion & Coupling

Q14: What is High Cohesion?
A14: A class does only one job well (focused).

Q15: What is Low Coupling?
A15: Classes are independent and interact only through simple interfaces.

Q16: Ideal design principle?
A16: High Cohesion + Low Coupling → modular, reusable code.


🔹 Python Basics from PDF

Q17: List vs Tuple vs Set vs Dictionary?
A17:

  • List → ordered, mutable, allows duplicates

  • Tuple → ordered, immutable

  • Set → unordered, unique values only

  • Dictionary → key-value pairs

Q18: What is Indentation in Python?
A18: Spaces at the start of a line that define blocks of code (instead of {}).

Q19: What does break and continue do in loops?
A19: break exits loop, continue skips current iteration.


🔹 Control Flow

Q20: Difference between Sequence, Selection, and Repetition?
A20:

  • Sequence → step-by-step execution

  • Selection → decision-making (if/else)

  • Repetition → looping (for, while)

Q21: Deterministic vs Non-Deterministic Loops?
A21:

  • Deterministic → fixed iterations (e.g., for i in range(5))

  • Non-Deterministic → unknown iterations (e.g., while user_input != "stop")


🔹 Functions & Recursion

Q22: What is a Function?
A22: A reusable block of code with name, parameters, and optional return value.

Q23: Difference between Function and Method?
A23:

  • Function = standalone block

  • Method = belongs to a class/object

Q24: What is Recursion?
A24: A function calling itself until a base case is reached.

Q25: Recursion vs Iteration?
A25:

  • Recursion → uses call stack, may risk stack overflow

  • Iteration → uses loops, more memory efficient


🔹 Algorithms

Q26: What is Bubble Sort?
A26: Repeatedly swap adjacent elements if out of order.

Q27: What is Selection Sort?
A27: Repeatedly find the minimum element and place it in order.

Q28: What is Insertion Sort?
A28: Insert each element into the correct position in sorted part.

Q29: What is Merge Sort?
A29: Divide & conquer → split list, sort halves, merge results.

Q30: What is Quick Sort?
A30: Choose a pivot, partition list, sort sublists recursively.


🔹 Math & Probability

Q31: What is Factorial?
A31: n! = n × (n-1) × ... × 1

Q32: What is a Permutation?
A32: Selection where order mattersnPk = n! / (n-k)!

Q33: What is a Combination?
A33: Selection where order does NOT matternCk = n! / (k!(n-k)!)


🔹 Advanced OOP in Python

Q34: What is self in Python classes?
A34: Refers to the current object instance (needed for attributes & methods).

Q35: Why use __ (double underscore) before variable names?
A35: To make them private → accessed only through getters/setters.

Q36: What is the difference between Public, Protected, and Private attributes in Python?
A36:

  • Public → normal (name) → accessible anywhere

  • Protected → _name → “internal use only” (by convention)

  • Private → __name → hidden, only accessible inside class


🔹 Flowcharts & Problem Solving

Q37: Why use Flowcharts for algorithms?
A37: Visual clarity, easier debugging, error detection, and communication.

Q38: Example: Game logic flashcard

Python SECTION 2 – Control Flow Conditionals – if, elif, else Loops Comprehensions

SECTION 2 – Control Flow (Weeks 2–3)


2.1 Conditionals – if, elif, else

📚 What: Conditionals let your program make decisions.
🧠 AI/ML Relevance:

  • Check accuracy thresholds before deployment

  • Decide model tuning steps based on loss value

  • Perform different preprocessing for text vs image datasets

💻 Example: Accuracy Evaluation

accuracy = 0.88

if accuracy > 0.9:
    print("Excellent model")
elif accuracy > 0.8:
    print("Good model, but can improve")
else:
    print("Needs more training")

Nested Conditions

📚 What: Condition inside another condition.
🧠 AI/ML Relevance:

  • Check multiple model performance metrics

  • Apply rules for different dataset conditions

💻 Example: Accuracy + Loss Check

accuracy = 0.92
loss = 0.15

if accuracy > 0.9:
    if loss < 0.2:
        print("Ready for deployment")
    else:
        print("Accuracy is fine, but reduce loss")

🏋 Exercise:
Write a conditional that:

  1. Checks if accuracy > 0.85

  2. If true, checks if loss < 0.15 → print "Excellent"

  3. Else print "Needs work"


2.2 Loops


For Loops

📚 What: Repeat code for a fixed number of iterations or over a collection.
🧠 AI/ML Relevance:

  • Iterate over datasets

  • Process batches in training

  • Apply transformations to every data point

💻 Example: Processing Dataset Batches

batches = ["Batch 1", "Batch 2", "Batch 3"]

for batch in batches:
    print(f"Processing {batch}")

While Loops

📚 What: Repeat until a condition becomes false.
🧠 AI/ML Relevance:

  • Continue training until loss is below a threshold

  • Keep collecting data until dataset size is reached

💻 Example: Training Until Loss Threshold

loss = 1.0
while loss > 0.1:
    print(f"Training... current loss = {loss}")
    loss -= 0.2
print("Training stopped: Loss threshold met")

Break & Continue

📚 What:

  • break → Stop the loop early

  • continue → Skip the rest of the current iteration

💻 Example: Stop Training Early

losses = [0.5, 0.3, 0.15, 0.09]

for loss in losses:
    if loss < 0.1:
        print("Loss is low enough, stopping early")
        break
    print(f"Current loss: {loss}")

💻 Example: Skip Bad Data

data_points = [1, None, 3, None, 5]

for point in data_points:
    if point is None:
        continue
    print(f"Processing: {point}")

range()

📚 What: Generates a sequence of numbers for looping.

💻 Example: 5 Epochs Training

for epoch in range(1, 6):
    print(f"Training Epoch {epoch}")

Loop Over Iterables

📚 What: Loop directly over lists, dicts, sets, tuples.
💻 Example: Looping Over Dictionary of Model Parameters

params = {"learning_rate": 0.001, "batch_size": 32, "epochs": 10}

for key, value in params.items():
    print(f"{key}: {value}")

🏋 Exercise:
Loop over a dictionary containing "model", "accuracy", and "loss" and print them in key: value format.


2.3 Comprehensions

📚 What: Shorter, cleaner way to create lists, sets, dicts from loops.
🧠 AI/ML Relevance: Quickly transform datasets without writing long loops.


List Comprehension

💻 Example: Squaring All Loss Values

losses = [0.5, 0.3, 0.15]
squared_losses = [loss**2 for loss in losses]
print(squared_losses)

Tuple Comprehension (Actually Generators in Python)

💻 Example: Generate Accuracy Values on the Fly

accuracies = (round(acc, 2) for acc in [0.82, 0.91, 0.88])
for acc in accuracies:
    print(acc)

Dict Comprehension

💻 Example: Mapping Model Names to Accuracies

models = ["Model_A", "Model_B", "Model_C"]
accs = [0.85, 0.90, 0.88]

model_performance = {model: acc for model, acc in zip(models, accs)}
print(model_performance)

Set Comprehension

💻 Example: Unique Label Extraction

labels = ["cat", "dog", "cat", "bird", "dog"]
unique_labels = {label for label in labels}
print(unique_labels)

🏋 Final Exercise for Section 2:
Given:

models = ["A", "B", "C"]
accuracies = [0.9, 0.85, 0.92]
  1. Create a dictionary mapping each model to its accuracy (dict comprehension)

  2. Create a list of only the accuracies above 0.88 (list comprehension)

  3. Loop over the dictionary and print "Model X has accuracy Y"




Python dictionary methods in action.

# Create a dictionary for months
months = {
    "January": 31,
    "February": 28,
    "March": 31,
    "April": 30,
    "May": 31,
    "June": 30
}

print("Original dictionary:", months)

1. Access values

print("Days in February:", months["February"])
print("Days in May (get method):", months.get("May"))
print("Non-existing month with default:", months.get("December", "Not Found"))

2. Add or update

months["July"] = 31  # Add
months["February"] = 29  # Update (Leap year)
print("After add/update:", months)

3. Remove — pop()

removed_days = months.pop("June")
print("Removed June (days =", removed_days, "):", months)

4. Remove last item — popitem()

last_item = months.popitem()
print("Removed last item:", last_item)
print("After popitem:", months)

5. Delete — del

del months["April"]
print("After deleting April:", months)

6. Clear dictionary

temp_months = months.copy()
temp_months.clear()
print("After clear:", temp_months)

7. Copy dictionary

months_copy = months.copy()
print("Copied dictionary:", months_copy)

8. Keys, Values, Items

print("Keys:", months.keys())
print("Values:", months.values())
print("Items:", months.items())

9. Loop through dictionary

for month, days in months.items():
    print(f"{month}: {days} days")

10. Check membership

print("Is 'March' in months?", "March" in months)
print("Is 'December' not in months?", "December" not in months)

11. Update with another dictionary

months.update({"August": 31, "September": 30})
print("After update:", months)

12. Dictionary comprehension

month_lengths = {month: len(month) for month in months}
print("Month name lengths:", month_lengths)

Tuple example similar to the list and set ones.
Tuples are ordered, immutable collections — so you can’t change items after creation (no append(), remove(), etc.), but you can still use many useful built-in functions.


# Create a tuple of fruits
fruits = ("apple", "banana", "cherry", "date", "elderberry", "banana")

print("Original tuple:", fruits)

1. Access elements by index

print("First fruit:", fruits[0])
print("Last fruit:", fruits[-1])

2. Slicing

print("First 3 fruits:", fruits[:3])
print("Fruits from index 2 onwards:", fruits[2:])

3. Count — count()

print("Count of 'banana':", fruits.count("banana"))

Counts occurrences of a value.


4. Index — index()

print("Index of 'cherry':", fruits.index("cherry"))

Finds the first occurrence of a value.


5. Length — len()

print("Number of fruits:", len(fruits))

6. Membership test

print("Is 'apple' in tuple?", "apple" in fruits)
print("Is 'mango' not in tuple?", "mango" not in fruits)

7. Concatenation

more_fruits = ("fig", "grape")
combined = fruits + more_fruits
print("Combined tuple:", combined)

8. Repetition

repeat_fruits = ("apple", "banana") * 2
print("Repeated tuple:", repeat_fruits)

9. Min / Max / Sum (works only if all items are same type)

numbers = (5, 2, 9, 1)
print("Min number:", min(numbers))
print("Max number:", max(numbers))
print("Sum:", sum(numbers))

10. Tuple unpacking

a, b, c, *rest = fruits
print("a:", a)
print("b:", b)
print("c:", c)
print("rest:", rest)

11. Convert to list (to modify) and back

temp_list = list(fruits)
temp_list.append("honeydew")
fruits = tuple(temp_list)
print("Modified tuple:", fruits)

Python set functions/methods with examples.
Remember: a set is unordered, does not allow duplicates, and elements must be immutable.


# Create a set of fruits
fruits = {"apple", "banana", "cherry", "date", "elderberry"}

print("Original set:", fruits)

1. Add — add()

fruits.add("fig")
print("After add:", fruits)

Adds a single item.


2. Update — update()

fruits.update(["grape", "honeydew"])
print("After update:", fruits)

Adds multiple items.


3. Remove — remove()

fruits.remove("banana")
print("After remove:", fruits)

Removes an item; error if not found.


4. Discard — discard()

fruits.discard("kiwi")  # No error if not found
print("After discard (kiwi):", fruits)

Removes item without error.


5. Pop — pop()

removed = fruits.pop()
print("Popped item:", removed)
print("After pop:", fruits)

Removes a random item (since sets are unordered).


6. Clear — clear()

temp_set = fruits.copy()
temp_set.clear()
print("After clear:", temp_set)

Removes all items.


7. Copy — copy()

fruits_copy = fruits.copy()
print("Copied set:", fruits_copy)

Shallow copy.


8. Union — union() / |

set_a = {"apple", "banana", "mango"}
set_b = {"banana", "kiwi", "orange"}
print("Union:", set_a.union(set_b))
print("Union (|):", set_a | set_b)

Combines sets, removes duplicates.


9. Intersection — intersection() / &

print("Intersection:", set_a.intersection(set_b))
print("Intersection (&):", set_a & set_b)

Items common to both sets.


10. Difference — difference() / -

print("Difference:", set_a.difference(set_b))
print("Difference (-):", set_a - set_b)

Items in the first set but not the second.


11. Symmetric Difference — symmetric_difference() / ^

print("Symmetric Difference:", set_a.symmetric_difference(set_b))
print("Symmetric Difference (^):", set_a ^ set_b)

Items in either set but not both.


12. isdisjoint()

print("Is disjoint?:", {"pineapple"} .isdisjoint({"mango"}))

True if no elements in common.


13. issubset() / issuperset()

print("Is subset?:", {"apple", "banana"}.issubset(set_a))
print("Is superset?:", set_a.issuperset({"banana"}))

14. len()

print("Number of fruits:", len(fruits))

Counts items in the set.


 Python list function / method with examples so you have a ready reference.


# Create a list of fruits
fruits = ["apple", "banana", "cherry", "date", "elderberry"]

print("Original list:", fruits)

1. Append — append()

fruits.append("fig")
print("After append:", fruits)

Adds an item to the end.


2. Insert — insert()

fruits.insert(2, "blueberry")
print("After insert:", fruits)

Inserts at a specific index.


3. Extend — extend()

fruits.extend(["grape", "honeydew"])
print("After extend:", fruits)

Adds multiple items.


4. Remove — remove()

fruits.remove("banana")
print("After remove:", fruits)

Removes first occurrence of a value.


5. Pop — pop()

popped = fruits.pop(3)
print("Popped item:", popped)
print("After pop:", fruits)

Removes by index (last item if no index given).


6. Clear — clear()

temp_list = fruits.copy()
temp_list.clear()
print("After clear:", temp_list)

Removes all items.


7. Index — index()

print("Index of cherry:", fruits.index("cherry"))

Finds the first occurrence of a value.


8. Count — count()

print("Count of 'apple':", fruits.count("apple"))

Counts how many times a value appears.


9. Sort — sort()

fruits.sort()
print("Sorted list:", fruits)

fruits.sort(reverse=True)
print("Reverse sorted list:", fruits)

Sorts in place (alphabetically by default).


10. Reverse — reverse()

fruits.reverse()
print("After reverse:", fruits)

Reverses order.


11. Copy — copy()

new_fruits = fruits.copy()
print("Copied list:", new_fruits)

Shallow copy of the list.


12. Slicing

print("First 3 fruits:", fruits[:3])
print("Last 2 fruits:", fruits[-2:])

Access sublists.


13. List Comprehension

long_names = [f for f in fruits if len(f) > 5]
print("Fruits with names longer than 5 letters:", long_names)

Create lists with conditions.


14. Length — len()

print("Number of fruits:", len(fruits))

Gets number of items.


15. Min / Max

print("Min fruit (alphabetically):", min(fruits))
print("Max fruit (alphabetically):", max(fruits))

import sys

# Join all arguments into one string

full_text = " ".join(sys.argv[1:])

# Example: full_text = "Arguments passed is <123> from command"

# Extract the part between < and >

start = full_text.find("<") + 1

end = full_text.find(">")

number = full_text[start:end]

print(number)
