My friends and I are doing a project for a Raspberry Pi competition (<-- nonessential information). We would like to have an online code editor for Python that is similar to the format of google docs. Preferably, it would store the code online, and you could access and edit it directly. I looked at github, but it seems like the group members can't work on it directly (they have to download the code, edit, and submit a pull request). If anybody knows of a good one, or knows how we could use github differently, that would be greatly appreciated!
