[FIXED] How to make arbitrary code blocks foldable in spyder

Issue

I want to group arbitrary blocks of code, say parts of a script. And then I want to be able to collapse them, just like I can collapse classes, function definitions and loops.

Solution

This can be done in Spyder 4 or later by defining a code block with a comment like so:

# %% lines below here can be collapsed
