Hi,
I am not sure, I understand the task completely, but maybe named
subpatterns and the groupdict data for the match objects may help?
for m in re.finditer(r"(?P<patternA>A)|(?P<patternB>B)", "QABCZ"):
print m.group(), m.groupdict()
A {'patternB': None, 'patternA': 'A'}
B {'patternB': 'B', 'patternA': None}
regards,
vbr
