Perhaps lookahead assertions are what you're
looking for?
import re
import string
non_overlap = re.compile(r'[0-9a-fA-F]{2}')
pairs = [ match.group(0) for match in
non_overlap.finditer(string.hexdigits) ]
print pairs
overlap = re.compile(r'[0-9a-fA-F](?=([0-9a-fA-F]))')
pairs = [ match.group(0) + match.group(1) for match in
overlap.finditer(string.hexdigits) ]
print pairs
