shift operators?

[Joshua Muskovitz]

<rant>
Is there a way to to right shift (>>) in a non-sign-extended way, short of
my evil hack:

def rshift(num, dist):
    if dist == 0:
        return num
    else:
        return ( (num >> dist) & (0x7fffffff >> (dist-1) ) )

I found it very annoying that there was no simple unsigned right shift in
Python.  And it made debugging my DES port a nightmare, until I figured out
what was going on.
