How to install both versions of Python 2.x and 3.x on windows 7 and switch between them?

Question

Python

Please tell me how to correctly install and run both versions of Python 2.x and 3.x in windows 7? I want to avoid version conflicts during installation. What and where should be registered manually? Which distributions to take - from the official site or are there solutions from third-party vendors? How do I switch between versions after installation?
Thank you!

Answer 1

They are installed separately and do not conflict. You can switch to ide. In the terminal, you can write python is version 2 or python 3 is version 3. Download https://www.python.org and don't invent it). The conflict may be between the versions of django and any libraries, in this case there is https://virtualenv.pypa.io/en/stable/ or docker.

Answer 2

What kind of conflicts are we talking about? They fit side by side with no problem.
