Python Operators

Operators in Python are used to perform operations on variables and values. Python provides various types of operators to handle different types of operations.

Types of Operators

• Arithmetic Operators: Used for mathematical operations
• Comparison Operators: Compare values
• Logical Operators: Used for logical expressions
• Bitwise Operators: Work at the binary level
• Assignment Operators: Assign values to variables
• Membership & Identity Operators: Check existence and identity

1. Arithmetic Operators

a = 10
b = 5
print(a + b)  # Addition
print(a - b)  # Subtraction
print(a * b)  # Multiplication
print(a / b)  # Division
print(a % b)  # Modulus
print(a ** b)  # Exponentiation
        

2. Comparison Operators

x = 10
y = 20
print(x == y)  # Equal to
print(x != y)  # Not equal to
print(x > y)   # Greater than
print(x < y)   # Less than
        

3. Logical Operators

a = True
b = False
print(a and b)  # Logical AND
print(a or b)   # Logical OR
print(not a)    # Logical NOT
        

4. Bitwise Operators

x = 5   # 0101
y = 3   # 0011
print(x & y)  # Bitwise AND
print(x | y)  # Bitwise OR
print(x ^ y)  # Bitwise XOR
print(~x)     # Bitwise NOT
        

5. Assignment Operators

a = 10
a += 5  # Same as a = a + 5
a -= 3  # Same as a = a - 3
a *= 2  # Same as a = a * 2
a /= 4  # Same as a = a / 4
        

6. Membership & Identity Operators

list1 = [1, 2, 3, 4, 5]
print(3 in list1)  # True
print(6 not in list1)  # True

x = 10
y = 10
print(x is y)  # True (same memory location)
print(x is not y)  # False
        

Conclusion

Operators are a crucial part of Python programming. Understanding their usage will help you write efficient and concise code.
