Python provides bitwise operators that work directly on the binary representation of numbers. These operators are mainly used in low-level programming, performance optimization, and working with binary data.
In this post, we will learn Python Bitwise Operators in detail with examples.
🧠 What are Bitwise Operators?
Bitwise operators perform operations on numbers at the bit (binary) level.
👉 In simple words:
- Computers store data in binary (0 and 1)
- Bitwise operators manipulate these bits directly
⚙️ Types of Python Bitwise Operators
Python supports the following bitwise operators:
& 1. Bitwise AND (&)
Compares each bit and returns 1 only if both bits are 1.
Example:
a = 5 # 0101
b = 3 # 0011
print(a & b)
Output:
1
| 2. Bitwise OR (|)
Returns 1 if at least one bit is 1.
Example:
a = 5 # 0101
b = 3 # 0011
print(a | b)
^ 3. Bitwise XOR (^)
Returns 1 if bits are different.
Example:
a = 5 # 0101
b = 3 # 0011
print(a ^ b)
~ 4. Bitwise NOT (~)
Inverts all bits (0 becomes 1, 1 becomes 0).
Example:
a = 5
print(~a)
<< 5. Left Shift (<<)
Shifts bits to the left (multiplies by 2).
Example:
a = 5
print(a << 1)
>> 6. Right Shift (>>)
Shifts bits to the right (divides by 2).
Example:
a = 5
print(a >> 1)
🧪 Bitwise Example with Binary View
a = 5 # 0101
b = 3 # 0011
print("AND:", a & b)
print("OR:", a | b)
print("XOR:", a ^ b)
📊 Python Bitwise Operators Summary
| Operator | Name | Description |
|---|---|---|
| & | AND | Both bits must be 1 |
| OR | ||
| ^ | XOR | Bits must be different |
| ~ | NOT | Inverts bits |
| << | Left Shift | Multiply by 2 |
| >> | Right Shift | Divide by 2 |
