From hexadecimal to one's complement in Python

Question

Is there an easy way to produce a one\'s complement in python?

For instance, if you take the hex value 0x9E, I need to convert it to 0x61.

Answer 1

Hah. just found out that python bin() return a string!

so we can have some fun at this!

for x in numbers: # numbers is a list of int
    b = bin(x)
    #print b # e.g. String 0b1011100101
    b = b.replace('0', 'x')
    b = b.replace('1', '0')
    b = b.replace('x', '1')
    b = b.replace('1b', '0b')
    #print b # String 0b0100011010
    print int(b, 2) # the decimal representation
