If in case we have different projects to work upon, and require to keep their dependencies separately, then Python virtual environments can be used. The python virtualenv makes it the most widely used feature in python.
Using virtual environment, you can make a different environment for each project that you’re working on. Let’s say you have a project and you want to work with python 3 and django 2.1. On other hand you’ve another project where you want to work with Python 3 and django 1.11.

It’s almost impossible for you to contribute because you’ll get a lot of errors due to the difference in django versions.
