Checks

• Checks that you are not using exact pins in your setup.py file – Exact pins in setup.py get baked into the packages you build and limit flexibility. Folks using your package will have to have that same exact version. If you want to update it, you have to build a new package.

• Checks that you are not reading a requirements.txt file and using it to populate install_requires in setup.py. I think that people mostly do this because they don’t understand the differences between setup.py and requirements.txt so I would advise reading https://caremad.io/2013/07/setup-vs-requirement/
