manipulating bits in python

[Greg Jorgensen]

Python has a full set of bitwise operators, which can be applied (only) to
integers and long integers:

x << y    left shift x by y bits
x >> y    right shift
x & y    bitwise and
x | y    bitwise or
x ^ y    bitwise xor
~x    bitwise negation

print "%x" % a    # print a as hex integer

I recommend the excellent book "Python Essential Reference" by David
Beazley.
