I'm trying to access the Jupyter Notebook and I'm getting the following message: "500 Internal Server Error ". What should I do?64 votes
Give students the code in .ipynb files to store locally rather than hosting them in a faulty cloud service
- This service is being paid for
- Your Jupyter Notebooks service is often down
- The course is paid for on a monthly basis (Time = Money)
You should provide the .ipynb files for student to store on their own device to complete lab sessions
Respond to user queries/ Get it fixed quick
Refund everyone for the time the service is down/intermittent.
Provide the service at no cost.50 votes

Intellisense-like popup-help. That is. hover over a function, class, etc. and get a short description
Most Python IDEs have some sort of pop-up help. e.g. hover over a function (built-in, library, user defined) and get a pop-up showing the signature.
Also highlight (e.g. with red squiggles) errors in syntax. Highlight in blue squiggles using a variable before definition, etc.6 votes
