如何在Python中按位互斥或两个字符串？

Question

我想在python中执行按位异或两个字符串，但是在python中不允许字符串的异或。我该怎么做 ？

Answer 1

您可以将字符转换为整数，然后将其转换为x或x：

l = [ord(a) ^ ord(b) for a,b in zip(s1,s2)]

如果由于XOR而需要一个字符串，这是一个更新的函数：

def sxor(s1,s2):    
    # convert strings to a list of character pair tuples
    # go through each tuple, converting them to ASCII code (ord)
    # perform exclusive or on the ASCII code
    # then convert the result back to ASCII (chr)
    # merge the resulting array of characters as a string
    return ''.join(chr(ord(a) ^ ord(b)) for a,b in zip(s1,s2))
