python represent binary numbers code example

Example 1: python int binary

print('{0:b}'.format(3))        # '11'
print('{0:8b}'.format(3))       # '      11'
print('{0:08b}'.format(3))      # '00000011'

def int2bin(integer, digits):
    if integer >= 0:
        return bin(integer)[2:].zfill(digits)
    else:
        return bin(2**digits + integer)[2:]
print(int2bin(3, 6))            # '000011'

Example 2: binary representation python

>>> bin(88)
'0b1011000'
>>> int('0b1011000', 2)
88
>>> 

>>> a=int('01100000', 2)
>>> b=int('00100110', 2)
>>> bin(a & b)
'0b100000'
>>> bin(a | b)
'0b1100110'
>>> bin(a ^ b)
'0b1000110'
