Setting up the Python 3 Environment
The Linux computers have a variety of Python environments installed on them. The system default on Fedora is Python version 2. We have also installed the Fedora-provided release of Python version 3.
If you need to use Python 3, you'll need to call it as python3. Run python3 -V to verify that you're using the right Python.
NOTE: The Python interpreter is called as python3.
