Debugging in Python, part 10: A logical error

Minimal reproducible examples
MP 148: How small can a minimum reproducible example be? Note: My workload has increased over the last month, and I haven't had time to finish the current debugging series. It should be wrapped up in a few more posts, and those posts should come out over the
Updating Python
MP 147: How do you clean up when you have too many Pythons lying around? About a year and a half ago, I wrote a post about how to update the version of Python you're using locally. I was hoping that would be a guide I could refer

Validating a new project
MP 142: Conference "open spaces" are a great place to get valuable feedback about new projects. Note: The debugging series will continue shortly. I spent a full week at PyCon, and my son graduated from middle school the day after I got back. Life has been busy. :) I
