def getline(filename, lineno): if lineno >= 1: for i, line in enumerate(open(filename)): if i == lineno - 1: return line return ''

Untested (I don't have a build quite recent enough).

This is for Challenge 2. The lineno-1 makes it likely slower than the others. If there was an optional argument to enumerate specifying 'startat=1', then I might catch up.
