A module is a very well-defined thing (it has a C level type
object). This is where code lives (eg, string.py). A package is
a (well defined) way of organizing modules. A directory
containing an __init__.py module is a package, and modules
therein can be imported as "<dirname>.<modulename>". A
library is an ill-defined thing; most probably used to mean a
directory of modules without an __init__.py, but since it has
no exact meaning in Python, it's hard to say for sure.
