The modules described in this chapter help you write software. For example, the :mod:pydoc module takes a module and generates documentation based on the module's contents. The :mod:doctest and :mod:unittest modules contains frameworks for writing unit tests that automatically exercise code and verify that the expected output is produced. :program:2to3 can translate Python 2.x source code into valid Python 3.x code.

The list of modules described in this chapter is:
