Feature request/idea: show how often each line of code was executed

[askvictor]

An idea I had some time ago while teaching Python was that it would be great for students to be able to see how often a particular line of code ran. This would allow students to better see what their code is doing. For example, it would let them see which branch of an if statement executed, or how often a particular loop looped. It is conceptually similar to coverage.py (I don't have much experience with that so don't know if it measures the count of each line executed, or just a yes/no). It might be represented by a heat-map type scale on the side of the window, perhaps with hover-text to show the actual number for that line.

No idea how feasible this is, nor if it would complicate the editor too much, but it would make a useful visual for learning.

btw - great work on the latest version!

I have no particular view of the usefulness of this but, technically, it could be supported by using the built-in trace module

I will convert this to a discussion in our new discussion board here at Github, as that's where we discuss feature requests from now on.
