📝 Python Assignment Operators — Updating & Managing Variables
Introduction 🌟
Assignment operators in Python are used to assign values to variables. They can also be used to update variables quickly by combining assignment with arithmetic or bitwise operations.
Note
💡 Assignment operators help you write cleaner, shorter, and more efficient code.
1. List of Assignment Operators 📋
| Operator | Meaning | Example |
|---|---|---|
| = | Simple assignment | x = 5 |
| += | Add & assign | x += 3 → x = x + 3 |
| -= | Subtract & assign | x -= 2 → x = x - 2 |
| *= | Multiply & assign | x *= 4 → x = x * 4 |
| /= | Divide & assign | x /= 2 → x = x / 2 |
| //= | Floor divide & assign | x //= 3 |
| %= | Modulus & assign | x %= 5 → x = x % 5 |
| **= | Exponent & assign | x **= 2 → x = x ** 2 |
| &= | Bitwise AND assign | x &= 3 |
| |= | Bitwise OR assign | x |= 2 |
| ^= | Bitwise XOR assign | x ^= 1 |
| >>= | Right shift assign | x >>= 1 |
| <<= | Left shift assign | x <<= 1 |
2. Basic Assignment (=) ✍️
basic_assignment.py
x = 10
y = 20
name = "Sathish"
print(x, y, name)3. Add & Assign (+=) ➕
add_assign.py
x = 5
x += 3 # x = x + 3
print(x) # 84. Subtract & Assign (-=) ➖
sub_assign.py
x = 10
x -= 4 # x = x - 4
print(x) # 65. Multiply & Assign (*=) ✖️
mul_assign.py
x = 6
x *= 2 # x = x * 2
print(x) # 126. Divide & Assign (/=) ➗
Division always results in a float.
div_assign.py
x = 9
x /= 2 # x = x / 2
print(x) # 4.57. Floor Divide & Assign (//=) 🔽
floor_div_assign.py
x = 9
x //= 2 # x = x // 2
print(x) # 48. Modulus & Assign (%=) 🧩
mod_assign.py
x = 10
x %= 3 # x = x % 3
print(x) # 19. Exponent & Assign (**=) ⚡
exp_assign.py
x = 4
x **= 2 # x = x ** 2
print(x) # 1610. Bitwise Assignment Operators 🧠
&= (AND assign)
and_assign.py
x = 6 # 110
x &= 3 # 011 -> 010 = 2
print(x)|= (OR assign)
or_assign.py
x = 4 # 100
x |= 1 # 001 -> 101 = 5
print(x)^= (XOR assign)
xor_assign.py
x = 5 # 101
x ^= 1 # 001 -> 100 = 4
print(x)>>= (Right shift assign)
right_shift.py
x = 8 # 1000
x >>= 2 # shift right → 0010 = 2
print(x)<<= (Left shift assign)
left_shift.py
x = 3 # 0011
x <<= 1 # shift left → 0110 = 6
print(x)11. Real-World Example 🌍
real_world.py
total = 0
price = float(input("Enter product price: "))
qty = int(input("Enter quantity: "))
total += price * qty
print(f"Total amount: Rs.{total:.2f}")Conclusion 🎉
