Searching a text file to find words matching a pattern

[Micael]

Hello everyone,

First I'm a beginner at Python and I'm trying to learn by testing a few different thing and now I'm stuck. First of all I use this text file ss100.txt. It's in Swedish so there is of course åäö in the file and that's a problem as well. My question is as follows:
How do I find all words with a pattern like this: hxxxgxx where x is an unknown character?

I tried this but it's not working and I ran out of ideas:

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import re

thefile = open("ss100.txt", "r")

for line in thefile:
    if re.match("h(.*)g(.*)(.*)", line) and len(line)==7:
        print line

A small example of the text file in the link above:

hopplös
hopplösa
hopplösare
hopplösares
hopplösas
hopplösast
hopplösaste
hopplösastes
hopplöse
hopplöses
hopplöshet
hopplösheten
hopplöshetens
hopplöshets
hopplöst

I'm looking for words with 7 characters starting with 'h' and a 'g' in position 5.
What is wrong with my code? Or is there a better way to do this.
