Assignment operators are used to assign values to variables. In Python, in addition to the simple = assignment, we have compound operators that perform an operation and assign the result to the same variable.
| Operator | Description | Example |
|---|---|---|
| = | Assigns value from right side to left side | x = 5 |
| += | Adds right side to left side and assigns result | x += 3 (x = x + 3) |
| -= | Subtracts right side from left side | x -= 2 (x = x - 2) |
| *= | Multiplies and assigns result | x *= 4 (x = x * 4) |
| /= | Divides and assigns result | x /= 2 (x = x / 2) |
| %= | Modulus and assigns result | x %= 3 (x = x % 3) |
| //= | Floor division and assigns result | x //= 2 |
| **= | Exponentiation and assigns result | x **= 3 (x = x ** 3) |
| &= | Bitwise AND and assigns result | x &= 2 |
| |= | Bitwise OR and assigns result | x |= 3 |
| ^= | Bitwise XOR and assigns result | x ^= 1 |
| >>= | Bitwise right shift and assigns result | x >>= 1 |
| <<= | Bitwise left shift and assigns result | x <<= 2 |
x = 10
x += 5 # x becomes 15
x *= 2 # x becomes 30
x //= 4 # x becomes 7
x **= 2 # x becomes 49
print(x) # Output: 49
