Change "Ready to use Python Enviorment" Example

[StanFromIreland]

The current example to someone who doesn't know what venvs are is not very clear. What about an example like such?

[fedora]$ python3
>>> print("Fedora Loves Python")
Fedora Loves Python

This is clearer to me.

Hey. Thanks for the suggestion. One of the purposes of this example is to show that venv is working out of the box (unlike e.g. in Debian/Ubuntu).
