Because comparing strings for equality in a loop is writing C in
Python, and that's
exactly what I'm trying to unlearn.

The proper way to do it is to produce a dictionary and look up a value
using a key.

    if item == 'searched.domain':
        return item...

Didn't think about doing it this way. Good point. Thx
