Python: how to edit an installed package?

by

You should never edit an installed package. Instead, install a forked version of package.

If you need to edit the code frequently, DO NOT install the package via pip install something and edit the code in ‘…/site_packages/…’

Instead, put the source code under a development directory, and install it with

$ python setup.py develop

or

$ pip install -e path/to/SomePackage

Or use a vcs at the first place

$ pip install -e git+https://github.com/lakshmivyas/hyde.git#egg=hyde

Put your changes in a version control system, and tell pip to install it explicitly.
