Applying my last regex to your test cases:
>>> r.match("xyz123aaabbab")
<_sre.SRE_Match object at 0x00B47F60>
>>> r.match("xyz123aabbaab")
>>> r.match("xayz123aaabab")
<_sre.SRE_Match object at 0x00B50020>
>>> r.match("xaaayz123abab")
>>> r.match("xaaayz123aaabab")
<_sre.SRE_Match object at 0x00B47F60>
>>> print r.pattern
^(?:.*?[^a])?(a{3})(?:b[ab]*)?$
You should also remember to check the (match_object).start(1) to verify that
it matches the "aaa" you want.
