New submission from Dan Wilt:
Working with re.sub() noted strange behavior with re.I set, seems like a bug.
Noted in both Python 2.7.12 and Python 3.5.2, Anaconda custom build (32-bit) on
Windows 7.
>>> import re
>>> re.sub('\.', '', '.....')
''
>>> re.sub('\.', '', '.....', re.I)
'...'
>>> re.sub('\.', '', '.....', re.L)
'.'
The first case is the expected behavior, the second and third aren't. Oddly
enough,
>>> re.sub('\.', '', '.....', re.L | re.I)
''
MWE file attached (python3)
Thanks, I'm a heavy python user, but not all that advanced - hope this is
helpful and I'm not just being stupid.
