Creating new list based on exact regex match in original list

[deanhystad]

re.match returns a MatchObject or None. Your code is taking the "string" attribute of the MatchObject and adding that to the list. The string attribute is the string passed to match. Take a look at MatchObject and see how it can provide the string you really want.

This may do what you want:

secondList = [i.group(0) for i in firstList if regex.match(i)]
