Python Bitwise operators help perform bit operations. All the decimal values will convert into binary values (bits sequence, i.e., 0100, 1100, 1000, 1001, etc.). Next, the Python bitwise operators work on these bits, such as shifting left to right or transforming bit values from 0 to 1 and vice versa.
The below table shows the different Python Bitwise operators and their meaning. For example, Consider x = 6 and y = 8 and their values in binary form are: x = 0110 and y = 1000
| Bitwise Operators | Meaning | Examples |
|---|---|---|
| & | Bitwise AND | X & Y = 0000 |
| | | OR | X | Y = 1110 |
| ^ | exclusive OR | X ^ Y = 1110 |
| ~ | complement | ~X = 00001001 (Not operator will convert all 0 into 1.) |
| << | Shift left | X << 1 = 00001100 (Bits will move 1 step left. If we use 2 or 3 then they shift accordingly) |
| >> | Shift right | Y >> 1 = 00000100 |
The Truth Table behind Python Bitwise Operators is:
| x | y | x & y | X | y | x ^ y |
|---|---|---|---|---|
| 0 | 0 | 0 | 0 | 0 |
| 0 | 1 | 0 | 1 | 1 |
| 1 | 0 | 0 | 1 | 1 |
| 1 | 1 | 1 | 1 | 0 |
Python Bitwise Operators Example
In this example, we are using two variables, a and b, whose values are 9 and 65. Next, we use them to show you the list of Bitwise operations.
a = 9
b = 65
print("Bitwise AND Operator On 9 and 65 is = ", a & b)
print("Bitwise OR Operator On 9 and 65 is = ", a | b)
print("Bitwise EXCLUSIVE OR Operator On 9 and 65 is = ", a ^ b)
print("Bitwise NOT Operator On 9 is = ", ~a)
print("Bitwise LEFT SHIFT Operator On 9 is = ", a << 1)
print("Bitwise RIGHT SHIFT Operator On 65 is = ", b >> 1)
In this Python bitwise operators program, we declared two integers, a and b, and assigned the values 9 and 65. The binary form of 9 = 00001001 and 65 = 01000001.
>>> a = 9 >>> b = 65
Lets see the Python calculations of these Operators
AND Operation = a&b
00001001 & 01000001 = 00000001 = 1
OR Operation on integer values = a | b
00001001 | 01000001 = 01001001 = 73
The Exclusive OR Operation = a^b
00001001 ^ 01000001 = 01001000 = 72
Right Shift Operation = b >> 1
01000001 >> 1 = 00100000 = 32
