Python 3 - Bitwise Operators Example


Advertisements

The following Bitwise operators are supported by Python language −

Operator Description Example
& Binary AND Operator copies a bit to the result if it exists in both operands (a & b) (means 0000 1100)
| Binary OR It copies a bit if it exists in either operand. (a | b) = 61 (means 0011 1101)
^ Binary XOR It copies the bit if it is set in one operand but not both. (a ^ b) = 49 (means 0011 0001)
~ Binary Ones Complement It is unary and has the effect of 'flipping' bits. (~a ) = -61 (means 1100 0011 in 2's complement form due to a signed binary number.
<< Binary Left Shift The left operands value is moved left by the number of bits specified by the right operand. a << 2 = 240 (means 1111 0000)
>> Binary Right Shift The left operands value is moved right by the number of bits specified by the right operand. a >> 2 = 15 (means 0000 1111)

Example

#!/usr/bin/python3

a = 60            # 60 = 0011 1100
b = 13            # 13 = 0000 1101
print ('a=',a,':',bin(a),'b=',b,':',bin(b))
c = 0

c = a & b;        # 12 = 0000 1100
print ("result of AND is ", c,':',bin(c))

c = a | b;        # 61 = 0011 1101 
print ("result of OR is ", c,':',bin(c))

c = a ^ b;        # 49 = 0011 0001
print ("result of EXOR is ", c,':',bin(c))

c = ~a;           # -61 = 1100 0011
print ("result of COMPLEMENT is ", c,':',bin(c))

c = a << 2;       # 240 = 1111 0000
print ("result of LEFT SHIFT is ", c,':',bin(c))

c = a >> 2;       # 15 = 0000 1111
print ("result of RIGHT SHIFT is ", c,':',bin(c))

Output

When you execute the above program it produces the following result −

a = 60 : 0b111100 b = 13 : 0b1101
result of AND is  12 : 0b1100
result of OR is  61 : 0b111101
result of EXOR is  49 : 0b110001
result of COMPLEMENT is  -61 : -0b111101
result of LEFT SHIFT is  240 : 0b11110000
result of RIGHT SHIFT is  15 : 0b111
