We have several techniques to install a Python module or package:
- We can write setup.py and use the distribution utilities module, distutils, to install the package into Python's lib/site-packages directory. This is described in detail in the Python Packaging Authority documentation. See https://www.pypa.io/en/latest/ for information. Building software for other people to install can be complex, and will often require sophisticated test cases using the tox tool to build environments, run tests, and create distribution kits. See https://tox.readthedocs.io/en/latest/ for more information.
- We can set the PYTHONPATH environment variable to include our packages and modules. We can set this temporarily in a shell, or we can set it more permanently by editing our ~/.bash_profile or the system's /etc/profile. We'll take a look at this later in...
