AttributeError: 'NoneType' re.search

[deanhystad]

You read the documentation?

re.search(pattern, string, flags=0)
Scan through string looking for the first location where the regular expression pattern produces a match, and return a corresponding Match. Return None if no position in the string matches the pattern; note that this is different from finding a zero-length match at some point in the string.

search returns None if there is no pattern match. You need to check that search() returned a match before using the match.
