You can find on the Internet various ways to have 'python' also refer to 'python3', but for the purposes of this tutorial we shall keep things simple and try to work with the bare minimum changes to the system.

This is possible because once we have activated our virtual environment, this environment understands that both 'python' and 'python3' are equivalent.
