Subject: [pycrypto] string XOR

This isn't a pycrypto question per se, but I thought someone might know the answer: I need to exclusive-OR two strings together.  I tried operator.XOR, but I get a runtime error:

    ke = operator.xor(kbpkb,ve)
TypeError: unsupported operand type(s) for ^: 'str' and 'str'

Is there a way to do this in native Python (I'm using 2.7.2), or must I use a library of some sort?

Thanks,
dpm
