You can use a sandbox when your computer needs to use multiple versions of Python, or use Docker;

Virtualenv is a python-brought, installed by Pip

1, virtualenv test1 set up sandbox

2. CD to sandbox directory, execute source bin/activate, start sandbox environment

3, deactivate exit sandbox environment

Note:

By default, the virtual environment relies on site packages in the system environment, which means that the installed third-party package in the system is also installed in the virtual environment.

If you do not want to rely on these package, then you can add parameters

--no-site-packages
