But it might be useful in some cases to (let's say) xor a string (or
bytestring):
The question is how common a need of these operations? If it is not
common enough, they are better be implemented as functions in a
third-party library.
The real question is, what does it mean to XOR a text string?
The OP explained this meaning with a sample implementation.
Are you aware that this can raise a ValueError for some input strings?
For example for '\U00100000' and '\U00010000'.
That works for me.
py> ''.join(chr(ord(a) ^ ord(b)) for a, b in zip('\U00100000', '\U00100000'))
'\x00'
Try with '\U00100000' and '\U00010000', not with '\U00100000' and
'\U00100000'.
