real time collaboration in google colaboratory

Question

Looking for a way to enable real time collaboration in a classroom setting while using Google Colaboratory for a IPython NoteBook. I know I can share the notebook, perform some operations etc, but not sure how to see my collaborators contributions in real time.

Halp?

edit 1: I imagined a scenario where one student group could input their code for one part of a problem, while a second student group could do the same, and both would be able to see what the other was doing at 1 minute intervals or so.

Answer 1

I'm going to more nicely phrase what has been discussed in the comments by Mr. Smith and Alaonde, but further elaborate on it for clarification:

The feature of Google Colab that allowed for edits to be made in real time by multiple users, has been shut down. I'm not entirely sure as to why, but I can assume it has to do with the amount of resources required on Google's end in order to keep Colaboratory free for all. However I did some searching and there are a few alternatives, though I doubt their as easy to use or as user friendly as Colaboratory:

1. Jupyter Notebooks (Needs no introduction)
2. Azure Notebooks (Microsoft Product)
3. Apache Zeppelin (Similar to Jupyter Notebooks)

Hopefully I was at least a little helpful!
