I ended up doing something similar:
# find the longest match
longest_match = ''
for word in re.findall('((0000:?)+)', ip6):
if len(word[0]) > len(longest_match):
longest_match = word[0]
# if we found a match, replace it with a colon
if longest_match:
ip6 = re.sub(longest_match, ':', ip6, 1)
Thanks!
