Here is the equivalent Python code.
This work slightly better, and handled 'colon-less' format correctly.

Code:

import sys, string
flip = string.maketrans('0123456789ABCDEFabcdef','FEDCBA9876543210543210')

for line in sys.stdin:
    i, j = line.find(':'), line.find('  ')
    s = line[i+1:j].translate(flip, ' ')    # flipped hexdigits only
    print line[:i+1], ' '.join(s[i:i-2:-1] for i in range(1-len(s),0,2))
