It's worth stressing this point a bit more. Lots of people have been using
this code, and some found bugs in it that are now fixed. This means that
whatever implementation of similar functionality you can come up with
yourself will most likely have more bugs and be less generally versatile.
And even if the standard library code doesn't fit your needs, start by
taking a deep look at what the Python Package Index (PyPI) offers instead
of writing your own.

Developer time is much better spent reusing other people's code and helping
to squash the remaining bugs in it than having everyone write their own
buggy code over and over.
