Sets in Python Definition Characteristics Creating Duplicate Efficiency Exercise

Definition of Sets
- Sets are used to store multiple items in a single variable.
- One of four built-in data types in Python for collections, alongside List, Tuple, and Dictionary.
Characteristics of Sets
- Unordered: Items do not have a defined order and appear in a random sequence.
- Unchangeable: Items cannot be modified after creation, but items can be added or removed.
- Unindexed: Items cannot be accessed via an index or key.
- No Duplicates: Each item must be unique within the set.
Creating a Set
- Sets are defined using curly brackets ({}).
- Example: myset = {"apple", "banana", "cherry"}.
- Sets can also be created using the set() constructor.
Duplicate Values
- Sets do not allow duplicate values.
- The values True and 1 are treated as duplicates.
- The values False and 0 are treated as duplicates.
Checking the Length
- Use the len() function to determine the number of items in a set.
- Example: len(myset).
Data Types in Sets
- Set items can be of any data type (e.g., strings, integers, booleans).
- A set can contain mixed data types.
Using the set() Constructor
- Example: set(("apple", "banana", "cherry")) creates a set.
Python Collections (Comparison)
- List: Ordered, changeable, allows duplicates.
- Tuple: Ordered, unchangeable, allows duplicates.
- Set: Unordered, unchangeable, unindexed, no duplicates.
- Dictionary: Ordered (Python 3.7+), changeable, no duplicates.
Exercise
- Example question: Which one is a set?
  - Correct answer: myset = {'apple', 'banana', 'cherry'}.
Efficiency and Usefulness
- Choosing the right collection type can improve efficiency, security, and retention of meaning.

💥 YouTube https://www.youtube.com/channel/UCJojbxGV0sfU1QPWhRxx4-A

💥 Blog https://localedxcelcambridgeictcomputerclass.blogspot.com/

1. Access Items in a Set

Indexing Not Allowed: Items in a set cannot be accessed using an index or a key.
Looping Through Items: You can loop through the set using a for loop.
- Example:
```
thisset = {"apple", "banana", "cherry"}
for x in thisset:
    print(x)
```
Check for Item Presence: Use the in keyword to check if a value exists in the set.
- Example:
```
print("banana" in thisset)
```
Check for Item Absence: Use the not in keyword to check if a value does not exist in the set.
- Example:
```
print("banana" not in thisset)
```

2. Changing Items in a Set

Items Cannot Be Changed: Once a set is created, its items cannot be modified.
Adding New Items: You can add new items to a set.

These points summarize all key aspects of accessing and working with items in a set.

💥 YouTube https://www.youtube.com/channel/UCJojbxGV0sfU1QPWhRxx4-A

💥 Blog https://localedxcelcambridgeictcomputerclass.blogspot.com/

1. Adding Items to a Set

Items Cannot Be Changed: Once a set is created, its existing items cannot be modified.

Adding New Items: You can add new items to a set using the add() method.

Example:

thisset = {"apple", "banana", "cherry"}
thisset.add("orange")
print(thisset)

2. Adding Items from Another Set

Use the update() Method: To add all items from one set to another, use the update() method.

Example:

thisset = {"apple", "banana", "cherry"}
tropical = {"pineapple", "mango", "papaya"}
thisset.update(tropical)
print(thisset)

3. Adding Any Iterable

Accepts Iterable Objects: The update() method can add items from any iterable object, such as tuples, lists, or dictionaries.
- Example (Adding a List):
```
thisset = {"apple", "banana", "cherry"}
mylist = ["kiwi", "orange"]
thisset.update(mylist)
print(thisset)
```

4. Exercise

Correct Syntax for Adding Items:
- Answer: add()

These points summarize how to add items to a set in Python.

Here is a list of all key points from the text:

1. Removing Items from a Set

Methods for Removing Items: Use the remove() or discard() methods.
- Example (Using remove()):
```
thisset = {"apple", "banana", "cherry"}
thisset.remove("banana")
print(thisset)
```
  Note: If the item does not exist, remove() will raise an error.
- Example (Using discard()):
```
thisset = {"apple", "banana", "cherry"}
thisset.discard("banana")
print(thisset)
```
  Note: If the item does not exist, discard() will NOT raise an error.

2. Removing a Random Item

Use the pop() Method: Removes a random item from the set.
- Example:
```
thisset = {"apple", "banana", "cherry"}
x = thisset.pop()
print(x)  # Removed item
print(thisset)  # Remaining set
```
  Note: Since sets are unordered, you cannot predict which item will be removed.
  Return Value: The removed item is returned by the pop() method.

3. Clearing the Set

Use the clear() Method: Empties the set.

Example:

thisset = {"apple", "banana", "cherry"}
thisset.clear()
print(thisset)  # Outputs: set()

4. Deleting the Set

Use the del Keyword: Deletes the set entirely.

Example:

thisset = {"apple", "banana", "cherry"}
del thisset
# Accessing `thisset` after this will raise an error as it no longer exists.

5. Exercise

Correct Syntax for Removing an Item:
- Answer: remove()

💥 YouTube https://www.youtube.com/channel/UCJojbxGV0sfU1QPWhRxx4-A

💥 Blog https://localedxcelcambridgeictcomputerclass.blogspot.com/

Here is a list of key points from the text:

1. Looping Through Set Items

Using a for Loop: You can iterate over items in a set using a for loop.
- Example:
```
thisset = {"apple", "banana", "cherry"}
for x in thisset:
    print(x)
```
  Note: Since sets are unordered, the order of items in the loop is not guaranteed.

2. Exercise

Correct Syntax for Looping Through Set Items:

Answer:

for x in {'apple', 'banana', 'cherry'}:
    print(x)

These points summarize how to loop through a set and identify the correct syntax for iterating over set items.

-------------

Python - Join Sets: Key Points

1. Joining Sets

union() method: Combines all items from both sets into a new set.

Example:

set1 = {"a", "b", "c"}
set2 = {1, 2, 3}
set3 = set1.union(set2)
print(set3)

| operator: An alternative to union() for joining sets.
- Example:
```
set3 = set1 | set2
print(set3)
```

2. Joining Multiple Sets

Using union() method: Add multiple sets in parentheses separated by commas.
- Example:
```
myset = set1.union(set2, set3, set4)
print(myset)
```
Using | operator: Separate multiple sets with additional | operators.
- Example:
```
myset = set1 | set2 | set3 | set4
print(myset)
```

3. Joining a Set and Other Data Types

union() method: Allows joining sets with lists, tuples, etc., resulting in a set.
- Example:
```
x = {"a", "b", "c"}
y = (1, 2, 3)
z = x.union(y)
print(z)
```
- Note: The | operator works only with sets.

4. Updating Sets

update() method: Adds all items from one set to another and modifies the original set.
- Example:
```
set1 = {"a", "b", "c"}
set2 = {1, 2, 3}
set1.update(set2)
print(set1)
```

5. Intersection of Sets

intersection() method: Returns a new set with only common items (duplicates) from both sets.
- Example:
```
set3 = set1.intersection(set2)
print(set3)
```
& operator: Alternative to intersection().
- Example:
```
set3 = set1 & set2
print(set3)
```
intersection_update() method: Keeps only duplicates in the original set.
- Example:
```
set1.intersection_update(set2)
print(set1)
```

6. Difference of Sets

difference() method: Returns items from the first set not present in the second set.
- Example:
```
set3 = set1.difference(set2)
print(set3)
```
- operator: Alternative to difference().
- Example:
```
set3 = set1 - set2
print(set3)
```
difference_update() method: Modifies the original set to keep items not in the other set.
- Example:
```
set1.difference_update(set2)
print(set1)
```

7. Symmetric Difference of Sets

symmetric_difference() method: Keeps all items except the duplicates from both sets.
- Example:
```
set3 = set1.symmetric_difference(set2)
print(set3)
```
^ operator: Alternative to symmetric_difference().
- Example:
```
set3 = set1 ^ set2
print(set3)
```
symmetric_difference_update() method: Keeps all except duplicates in the original set.
- Example:
```
set1.symmetric_difference_update(set2)
print(set1)
```

8. Special Cases

Duplicate Value Consideration:
- True and 1 are considered the same value.
- False and 0 are considered the same value.
- Example:
```
set1 = {"apple", 1, "banana", 0}
set2 = {False, "google", 1, True}
set3 = set1.intersection(set2)
print(set3)
```

9. Exercise

Correct Syntax for Joining Sets:

Answer:
```
set3 = set1.union(set2)
```

Python tuples Accessing Tuple Items by Index

Definition of Tuples
- Tuples are used to store multiple items in a single variable.
- One of the four built-in data types in Python to store collections of data: List, Tuple, Set, and Dictionary.
- Tuples are ordered and unchangeable collections.
- Written with round brackets ( ).

Tuple Example

mytuple = ("apple", "banana", "cherry")
print(mytuple)

Tuple Properties
- Ordered: Items have a defined order that does not change.
- Unchangeable: Items cannot be modified, added, or removed once the tuple is created.
- Allows Duplicates: Tuples can contain duplicate values.
Tuple Indexing
- Tuple items are indexed starting from [0] for the first item, [1] for the second, and so on.

Example of Duplicate Values

thistuple = ("apple", "banana", "cherry", "apple", "cherry")
print(thistuple)

Tuple Length
- Use the len() function to determine the number of items in a tuple.
  Example:
```
thistuple = ("apple", "banana", "cherry")
print(len(thistuple))
```

Tuple With One Item

To create a single-item tuple, include a trailing comma:

thistuple = ("apple",)  # Tuple
print(type(thistuple))
thistuple = ("apple")  # Not a tuple
print(type(thistuple))

Tuple Items - Data Types
- Items in a tuple can be of any data type. Examples:
  - Strings: tuple1 = ("apple", "banana", "cherry")
  - Integers: tuple2 = (1, 5, 7, 9, 3)
  - Booleans: tuple3 = (True, False, False)
- A tuple can also mix different data types:
```
tuple1 = ("abc", 34, True, 40, "male")
```
Tuple Data Type
- Tuples are objects of the data type <class 'tuple'>. Example:
```
mytuple = ("apple", "banana", "cherry")
print(type(mytuple))
```

The tuple() Constructor

Tuples can also be created using the tuple() constructor. Example:

thistuple = tuple(("apple", "banana", "cherry"))  # Double round brackets
print(thistuple)

Python Collections Overview
- List: Ordered, changeable, allows duplicates.
- Tuple: Ordered, unchangeable, allows duplicates.
- Set: Unordered, unindexed, no duplicates, items are unchangeable (but can be added/removed).
- Dictionary: Ordered (from Python 3.7 onwards), changeable, no duplicate keys.
Choosing a Collection Type
- Understanding the properties of collection types is essential for efficiency, meaning retention, and security.
Exercise Example

Identify the tuple:

Accessing Tuple Items by Index
- Use square brackets [ ] to access tuple items by their index.
- Example:
```
thistuple = ("apple", "banana", "cherry")
print(thistuple[1])  # Output: banana
```
- Note: The first item has index 0.
Negative Indexing
- Negative indexing starts from the end of the tuple.
- -1 refers to the last item, -2 refers to the second last item, and so on.
- Example:
```
thistuple = ("apple", "banana", "cherry")
print(thistuple[-1])  # Output: cherry
```
Range of Indexes
- Specify a range of indexes to retrieve multiple items.
- The result is a new tuple with the specified items.
- Example:
```
thistuple = ("apple", "banana", "cherry", "orange", "kiwi", "melon", "mango")
print(thistuple[2:5])  # Output: ('cherry', 'orange', 'kiwi')
```
- Note: The range includes the start index but excludes the end index.

Leaving Out Start Value

Leaving out the start index begins the range from the first item.

Example:

thistuple = ("apple", "banana", "cherry", "orange", "kiwi", "melon", "mango")
print(thistuple[:4])  # Output: ('apple', 'banana', 'cherry', 'orange')

Leaving Out End Value

Leaving out the end index continues the range to the last item.

Example:

thistuple = ("apple", "banana", "cherry", "orange", "kiwi", "melon", "mango")
print(thistuple[2:])  # Output: ('cherry', 'orange', 'kiwi', 'melon', 'mango')

Range of Negative Indexes

Use negative indexes to specify a range starting from the end.

Example:

thistuple = ("apple", "banana", "cherry", "orange", "kiwi", "melon", "mango")
print(thistuple[-4:-1])  # Output: ('orange', 'kiwi', 'melon')

Check if an Item Exists

Use the in keyword to check if a specific item exists in a tuple.

Example:

thistuple = ("apple", "banana", "cherry")
if "apple" in thistuple:
    print("Yes, 'apple' is in the fruits tuple")

Exercise Question
- What is the index number of the first item?
  Answer: 0.

Here are all the key points summarized from the provided text about updating tuples in Python:

1. Tuples Are Unchangeable (Immutable)

Tuples are immutable, meaning you cannot change, add, or remove items once created.
However, workarounds exist.

2. Change Tuple Values

Tuples themselves cannot be directly modified, but you can:
1. Convert the tuple into a list.
2. Modify the list.
3. Convert the list back into a tuple.

Example:

x = ("apple", "banana", "cherry")
y = list(x)
y[1] = "kiwi"
x = tuple(y)
print(x)  # Output: ('apple', 'kiwi', 'cherry')

3. Add Items to a Tuple

Tuples do not have an append() method, but you can add items using two approaches:

(1) Convert into a List:
- Convert the tuple into a list, add the new item(s), and convert it back into a tuple.
  Example:
```
thistuple = ("apple", "banana", "cherry")
y = list(thistuple)
y.append("orange")
thistuple = tuple(y)
print(thistuple)  # Output: ('apple', 'banana', 'cherry', 'orange')
```
(2) Add Tuple to Tuple:
- Create a new tuple with the additional item(s) and concatenate it to the existing tuple.
  Example:
```
thistuple = ("apple", "banana", "cherry")
y = ("orange",)
thistuple += y
print(thistuple)  # Output: ('apple', 'banana', 'cherry', 'orange')
```
Note: When creating a tuple with one item, always include a comma (,) after the item to identify it as a tuple.

4. Remove Items from a Tuple

Direct removal is not possible because tuples are immutable.
Workaround: Convert the tuple into a list, remove the item(s), and convert it back into a tuple.

Example:

thistuple = ("apple", "banana", "cherry")
y = list(thistuple)
y.remove("apple")
thistuple = tuple(y)
print(thistuple)  # Output: ('banana', 'cherry')

Delete the Entire Tuple:

Use the del keyword to delete the entire tuple.
Example:

thistuple = ("apple", "banana", "cherry")
del thistuple
# print(thistuple) will raise an error because the tuple no longer exists

5. Exercise Question

You cannot change the items of a tuple, but there are workarounds. Which of the following suggestions will work?

Correct Answer:
- Convert tuple into a list, change item, convert back into a tuple.
Incorrect Answers:
- Convert tuple into a set, change item, convert back into a tuple.
- Convert tuple into a dictionary, change item, convert back into a tuple.

Here are all the key points summarized from the provided text about unpacking tuples in Python:

1. Packing a Tuple

Packing refers to assigning multiple values to a tuple.
Example:

fruits = ("apple", "banana", "cherry")

2. Unpacking a Tuple

Unpacking is extracting the values from a tuple into individual variables.
The number of variables must match the number of items in the tuple, unless an asterisk is used.
Example:

fruits = ("apple", "banana", "cherry")
(green, yellow, red) = fruits

print(green)   # Output: apple
print(yellow)  # Output: banana
print(red)     # Output: cherry

3. **Using Asterisk (`*`)**

If the number of variables is less than the number of tuple items, an asterisk (*) can be used to collect the remaining values into a list.

Example 1: Assign the remaining values to the last variable:

fruits = ("apple", "banana", "cherry", "strawberry", "raspberry")
(green, yellow, *red) = fruits

print(green)   # Output: apple
print(yellow)  # Output: banana
print(red)     # Output: ['cherry', 'strawberry', 'raspberry']

Example 2: Assign the remaining values to a middle variable:

The asterisk can be added to a variable that is not the last one. Python will adjust values to fit the remaining variables.

fruits = ("apple", "mango", "papaya", "pineapple", "cherry")
(green, *tropic, red) = fruits

print(green)   # Output: apple
print(tropic)  # Output: ['mango', 'papaya', 'pineapple']
print(red)     # Output: cherry

4. Exercise Question

Consider the following code:

fruits = ('apple', 'banana', 'cherry')
(x, y, z) = fruits
print(y)

What will be the value of y?

Correct Answer: banana

--------------------------

Here are all the key points about looping through tuples in Python:

1. Loop Through a Tuple Using a `for` Loop

You can directly iterate through tuple items using a for loop. Example:

thistuple = ("apple", "banana", "cherry")
for x in thistuple:
    print(x)

2. Loop Through a Tuple Using Index Numbers

You can iterate through a tuple by referring to its index numbers.
Use the range() and len() functions to create an iterable sequence of index numbers. Example:

thistuple = ("apple", "banana", "cherry")
for i in range(len(thistuple)):
    print(thistuple[i])

3. Loop Through a Tuple Using a `while` Loop

A while loop can also be used to iterate through a tuple.
Use the len() function to determine the length of the tuple.
Start at index 0 and increase the index by 1 after each iteration. Example:

thistuple = ("apple", "banana", "cherry")
i = 0
while i < len(thistuple):
    print(thistuple[i])
    i += 1

4. Exercise Question

What is the correct syntax for looping through the items of a tuple?

Options:

for x in ('apple', 'banana', 'cherry'):
    print(x)

for x in ('apple', 'banana', 'cherry')
    print(x)

foreach x in ('apple', 'banana', 'cherry')
    print(x)

Correct Answer:
Option 1

for x in ('apple', 'banana', 'cherry'):
    print(x)

---------------------

Here are the key points about joining and multiplying tuples in Python:

1. Join Two Tuples Using the + Operator

You can join two or more tuples by using the + operator.
Example:

tuple1 = ("a", "b", "c")
tuple2 = (1, 2, 3)

tuple3 = tuple1 + tuple2
print(tuple3)  # Output: ('a', 'b', 'c', 1, 2, 3)


2. Multiply Tuples Using the * Operator

You can multiply a tuple to repeat its content a specific number of times using the * operator.
Example:

fruits = ("apple", "banana", "cherry")
mytuple = fruits * 2

print(mytuple)  # Output: ('apple', 'banana', 'cherry', 'apple', 'banana', 'cherry')


3. Exercise Question
What is the correct syntax for joining tuple1 and tuple2 into tuple3?
Options:

tuple3 = join(tuple1, tuple2)
tuple3 = tuple1 + tuple2
tuple3 = [tuple1, tuple2]

Correct Answer:

Option 2
tuple3 = tuple1 + tuple2
----------------------------------
Python - Tuple Methods
Python provides two built-in methods for working with tuples:

1. count() Method

Description: Returns the number of times a specified value occurs in the tuple.
Example:
thistuple = (1, 2, 3, 2, 2, 4)
occurrences = thistuple.count(2)
print(occurrences)  # Output: 3




2. index() Method

Description: Searches the tuple for a specified value and returns the position (index) of its first occurrence.
Example:
thistuple = (1, 2, 3, 4, 5)
position = thistuple.index(3)
print(position)  # Output: 2




These methods can be applied directly to any tuple to analyze or retrieve specific data.
