I really don't think I can agree with this. The core Perl5 install comes
with a great number of modules. cpan.org is overflowing with modules of
In looking at switching to Python for larger projects, one of my worries
has been a _lack_ of modules to draw on compared to Perl.

My goal is to learn Python, not to create a solution to a problem. The
program I chose to reproduce just happened to do something an existing
module already does. If I used that module, I'd be defeating the purpose
of writing the program, which is to learn how to process text from a file
and see how it compares to what I already know in Perl. If I let a module
do all the work for me, I do not learn what I set out to learn.
