re.split ('[ ,]', source)
This is probably not what you want in dealing with
human-created text:
>>> re.split('[ ,]', 'foo bar, spam,maps')
['foo', '', 'bar', '', 'spam', 'maps']
I think you've got a typo in there... this is what I get:
--> re.split('[ ,]', 'foo bar, spam,maps')
['foo', 'bar', '', 'spam', 'maps']
I would add a * to get rid of that empty element, myself:
--> re.split('[ ,]*', 'foo bar, spam,maps')
['foo', 'bar', 'spam', 'maps']
It's better to use + instead of * because you don't want it to be a
zero-width separator. The fact that it works should be treated as an
idiosyncrasy of the current re module, which can't split on a
zero-width match.
