Regex: Matching a space-joined list of words, excluding last whitespace
- by Jesper
How would I match a space separated list of words followed by whitespace and some optional numbers?
I have this:
>>> import re
>>> m = re.match('(?P<words>(\w+\s+)+)(?P<num>\d+)?\r\n', 'Foo Bar 12345\r\n')
>>> m.groupdict()
{'num': '12345', 'words': 'Foo Bar '}
I'd like the words group to not include the last whitespace(s) but I can't figure this one out. I could do a .strip() on the result but that's not as much fun :)
Some strings to test and wanted result:
'Foo & Bar 555\r\n' => {'num': '555', 'words': 'Foo & Bar'}
'Hello World\r\n' => {'num': None, 'words': 'Hello World'}
'Spam 99\r\n' => {'num': 99, 'words': 'Spam'}
'Number 1 666\r\n' => {'num': 666, 'words': 'Number 1'}
