mike bayer <[email protected]> added the comment:
for those watching this would be the findall() case which is consistent between
pythons:
import re
for reg in [
'VARCHAR(30) COLLATE "en_US"',
'VARCHAR(30)'
]:
print(re.findall(r'(?: COLLATE.*)?$', reg))
output (all pythons):
[' COLLATE "en_US"', '']
['']
so yes there are two matches for one and only one for the other.
