• Definition: Operators perform operations on variables and values.
• Example: print(10 + 5)

Categories of Python Operators

1. Arithmetic operators
2. Assignment operators
3. Comparison operators
4. Logical operators
5. Identity operators
6. Membership operators
7. Bitwise operators

Details of Each Operator Category

1. Python Arithmetic Operators

• Operators and their meanings:
  • + (Addition)
  • - (Subtraction)
  • * (Multiplication)
  • / (Division)
  • % (Modulus)
  • ** (Exponentiation)
  • // (Floor division)

2. Python Assignment Operators

• Assign values to variables:
  • =
  • +=
  • -=
  • *=
  • /=
  • %=
  • //=
  • **=
  • &=
  • |=
  • ^=
  • >>=
  • <<=
  • := (Walrus operator)

3. Python Comparison Operators

• Compare two values:
  • == (Equal)
  • != (Not equal)
  • > (Greater than)
  • < (Less than)
  • >= (Greater than or equal to)
  • <= (Less than or equal to)

4. Python Logical Operators

• Combine conditional statements:
  • and
  • or
  • not

5. Python Identity Operators

• Compare object identity (memory location):
  • is
  • is not

6. Python Membership Operators

• Test for presence in a sequence:
  • in
  • not in

7. Python Bitwise Operators

• Compare binary numbers:
  • & (AND)
  • | (OR)
  • ^ (XOR)
  • ~ (NOT)
  • << (Left shift)
  • >> (Right shift)

---

Python Operator Precedence

• Defines the order of evaluation in expressions.
• Precedence order (highest to lowest):
  1. () Parentheses
  2. ** Exponentiation
  3. +x, -x, ~x Unary operations
  4. *, /, //, % Multiplication, division, floor division, modulus
  5. +, - Addition and subtraction
  6. <<, >> Bitwise shifts
  7. & Bitwise AND
  8. ^ Bitwise XOR
  9. | Bitwise OR
  10. Comparisons, identity, and membership operators
  11. not Logical NOT
  12. and Logical AND
  13. or Logical OR

---

Examples

1. Parentheses have the highest precedence:

   print((6 + 3) - (6 + 3))  
   

2. Multiplication is evaluated before addition:

   print(100 + 5 * 3)  
   

3. Operators with the same precedence are evaluated left to right:

   print(5 + 4 - 7 + 3)

x = 5  
x += 3  
print(x)
