You can still run Python 2 by typing python2, python2.7, or /usr/bin/python. Note: to see the available packages in the Python 2.7 collection, search for python27. If you use a version number such as python3.6 and you haven't enabled/activated the right environment, you'll get a clean and easy-to-understand command not found error. Note: for virtualenv, using python3.6 -m virtualenv is recommended instead of using the virtualenv command. Note: you should already have run scl enable before activating the virtual environment. Ansible is written in Python, uses Jinja2 for templating, and provides higher-level abstractions for many system tasks. needs to run on a specific version of the language because it requires a certain dependency that is present in older versions but changes in newer versions.

The commands to create the virtual environments differ only in the module name used. However, I want to be able to choose a particular virtual environment in which to run the script. pip --user installs use ~/.local, which can be obscured by enabling software collections and/or activating virtual environments. Therefore, the changes made by scl enable will affect only the current terminal session or anything started from it. Some subtle (hard to diagnose) problems can occur if you wind up unintentionally mixing versions. Imagine a scenario where you are working on two web based python projects and one of them uses a Django 1.9 and the other uses Django 1.10 and so on.
