l = "wisconsin_state.txt"
l.split(".")[0].split("_")[-1]
Explanation:
---
the split(".")[0] part takes everything before the "."
the split("_")[-1] part selects in the last element in the list of

A pair of solutions:
>>> s = "central_african_republic_province.txt"
>>> s.rsplit("_", 1)[-1].split(".")[0]
'province'
>>> import re
>>> p = re.compile(r"_ ([^_]+) \.", re.VERBOSE)
>>> s = """\
... wisconsin_state.txt
... french_guiana_district.txt
... central_african_republic_province.txt"""
>>>
