Modules

• A module is a file containing definitions and implementations of classes, functions that can be used inside another program, and variables.

• Do not use import * because it affects readability.

• dir(<package_name>) returns the names defined by a module.

How to make a project installable with pip

• One directory with one module and a setup.py file is enough to make it installable via pip.

• some_module.py is the code to be shared.

Example

• In the <directory>, both module and setup.py are located pip install ./<directory>

some_module_proj/ |- setup.py |- some_module.py

$ >> pip install ./some_module_proj

$ >> python

>>> from some_module import some_func >>> some_func() >>> exit()
