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