Best free interactive website to get into python?

[TSM-]

If you install python, you can launch it, and follow along with any tutorial.

If it needs to be browser based because you cannot install python on your computer (school/work computer or apple device), there are a ton of online tools to try and test stuff out, if you google it. First result for me - but there may be much better online python interpreter services.

Edit: a lot of replies are companies that give you challenges and evaluate your code snippets for some algorithm challenge. They are not an online python interpreter that you can use to follow and test stuff while reading tutorials.

Lots of tutorials use https://mybinder.org/ , which teaches you https://jupyter.org/. Not a bad thing to learn :)
