I do it for my cat

I learnt about this early in the Python Course. I filed it away in my brain. Now that I'm learning about Django, it has come up again and all I can think is Virtual Environment who?? So for the benefit of my future junior software developer self, a virtual environment is a tool that enables one to keep  dependencies required by different projects together by creating an environment for them. In plain speak, I have a hypothetical box for Project A. It requires dependencies with specific versions- Dependency A ver 1.0, Dependency B ver 1.4, Dependency C ver 2.3.I put all these dependencies(with their specific versions) in that box. Now comes along Project B, which requires a different set of dependencies with different versions. Perhaps because the versions have since been updated. I store them all in hypothetical box 2. So each one of these hypothetical boxes is a virtual environment. It allows me to use different dependencies with my different projects because dependencies change...
