Reading the fine manual, http://docs.python.org/library/re.html : re.match(pattern, string[, flags]) If zero or more characters at the beginning of string match the regular expression pattern, return a corresponding MatchObject instance. Return None if the string does not match the pattern; note that this is different from a zero-length match. ***Note: If you want to locate a match anywhere in string, use search() instead.*** re.search(pattern, string[, flags]) Scan through string looking for a location where the regular expression pattern produces a match, and return a corresponding MatchObject instance. 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.
