Right. The famous stdlib where once good libraries go to die so you instead depend on the latest community replacement choice.

Also argparse for Clap:

https://docs.python.org/3/library/argparse.html

To highlight the problem for Python: Python's standard library has getopt, optparse, and now argparse. I don't think they set out to offer 3 argument parsing libs, one of which is marked superseded, but here we are.

And ironically with the exception of the python sqlite3 module, the rust alternatives are much higher quality, IMO.

I wouldn't start a company behind it but tkinter is perfectly fine for basic guis. It has its quirks but who doesn't?
