[SOLVED] Workaround for running python 2 programs?

[arvamircea]

Hello o/

I know that Gentoo has stopped supporting python 2. However. I find myself needing to run a lot of programs that have not updated they code to python 3.
Running a program with a different version of python is fairly straight forward "python2.x yourProgram.py" however many programs require libraries that are not available for python 2 anymore. Fore example:
-the bitcoin P2Pool requires "twisted" and "python-argparse"
-a cjdns tool called "cjdnsmap" requires the "httplib2"
-etc

What is the easiest/foolproof way of running python 2 programs on gentoo that require python 2 libraries?

In my development work I use different versions of python and I use pyenv to switch between them. It installs the requested version of python into user home directory and does not pollute the system.

Thank you spica! I will see how pyenv works and use it.
