First steps...

Where to practice:

The picture below shows the online terminal where I'll do most stuff, repl.it.

On the left side of the picture is the "Python interpreter prompt", also known as "the place where you can write". On it's right side we will be able to see "answers" from the code and interact with it.

If you want to try anything from this page by yourself, open the terminal and paste the code you want to try, then press "run"

What to practice:

This page also has an online course that teaches the basics step by step! You might need to make an account first. On the learn/teach tab there is a python course, how lucky.
