I never had a issue with loops. If I feel something is off, I terminate, check code, and fix it.

This. I rarely boot up Python for the tasks I need to do, and if they are, they are one of the following:

• Assistant code for other coding language
• Throwaway script
• Prototype before using a faster language

As always, I do image processing. I’m a G’MIC filter developer. Recently, did some code changes to my combinatorics tools to be insensitive to multi-threaded strategy.
