hex string into binary format?

[Tertius Cronje]

Hi,

How do I get a hexvalued string to a format recognized for binary
calculation?


import binascii
s1 = '1C46BE3D9F6AA8 20'
s2 = '8667B5236D89CD 46'

i1 = binascii.unhexl ify(s1)
i2 = binascii.unhexl ify(s2)
x = i1 ^i2

TypeError: unsupported operand type(s) for ^: 'str' and 'str'

Many TIA
T

i1=int(s1,16)
i2=int(s2,16)

Try this instead:
i1 = long(s1, 16)
i2 = long(s2, 16)
[color=blue]
> x = i1 ^i2[/color]

You're going to be embarrassed.

No imports at all:

s1 = '1C46BE3D9F6AA8 20'
s2 = '8667B5236D89CD 46'
i1 = int(s1,16)
i2 = int(s2,16)
x = i1 ^ i2
print hex(x)
