Repl.it is a free web service that allows you to write and run python code without having to install anything. All of your work will save in the cloud and so you can use it from any device, anywhere in the world, as long as you have an internet connection.

If this is your first time using Repl.it, please sign up using an existing Google account, so that you can save your work and log back in next time to continue with what you were doing.

Once signed up, click on the link on the left, go to the "learn_programming" Repl on my profile and once there, click the "Fork" button at the top middle. This will take a copy of my folders and files and save it to your profile, so that you can edit and do what you like with it.

Find the files on the left hand side and then start with "1-HelloWorld.py".

Oh, and make sure you actually read the instructions properly. There's a lot of writing in each file, but it's important and I've tried to make it as least boring as possible.
