Which I think is the problem. Python has generators/iterators, which
work very well with the 'for' loop.

Thus the ugliness of e.g:

>while True:
>    line=infile.readline()
>    if line == '':
>        break

is an excellent opportunity to introduce generators/iterators in
general (and the built in iterator of files in particular):

>for line in infile:
