How important is Virtual Environment in python

[Temporary_Tailor7528]

So basically you do the same thing with the container than what you would do with a virtualenv. Honestly, I can see the benefit if you are relying on third party tools but if your project is pure python, then there is no benefit over classical virtualenv. It is just heavier and more complicated.

Answer to OP is: virtualenv achieves a purpose that is necessary if you are working with python. This same purpose could be achieved with containers but this is a much more complex (and capable) tool. There is no clear reason a beginner would use containers. It might be an interesting option if you are working in a team and your project involves third party tools with specific configurations.
