How to use values stored in variables as case patterns?
I’m trying to understand the new structural pattern matching syntax in Python 3.10. I understand that it is possible to match on literal values like this:

Argparse with required subparser
I’m using Python 3.4, I’m trying to use argparse with subparsers, and I want to have a similar behavior to the one in Python 2.x where if I don’t supply a positional argument (to indicate the subparser/subprogram) I’ll get a helpful error message. I.e., with python2 I’ll get the following error message:
warning about too many open figures
In a script where I create many figures with fix, ax = plt.subplots(...), I get the warning RuntimeWarning: More than 20 figures have been opened. Figures created through the pyplot interface (matplotlib.pyplot.figure) are retained until explicitly closed and may consume too much memory.

PyEval_InitThreads in Python 3: How/when to call it? (the saga continues ad nauseam)
Basically there seems to be massive confusion/ambiguity over when exactly PyEval_InitThreads() is supposed to be called, and what accompanying API calls are needed. The official Python documentation is unfortunately very ambiguous. There are already many questions on stackoverflow regarding this topic, and indeed, I’ve personally already asked a question almost identical to this one, so I won’t be particularly surprised if this is closed as a duplicate; but consider that there seems to be no definitive answer to this question. (Sadly, I don’t have Guido Van Rossum on speed-dial.)
Tkinter resize background image to window size
Trying to set up a background for my tkinter window. I have a square background image, which fades to black around the edges, and then the main window has a black background. The image is placed over the background, and if the window is wider than it is tall, the image centers itself in the middle over the black background, and it all looks very nice.
