OK, I feel like an absolute noob:
I just spent hours debugging that I left a comma at the end of a
#Python assignment, so the value became a tuple instead of the object I wanted 🤦
The library I passed the value to also has very liberal typing so it failed quietly, and the IDE didn't tip me off because I overwrote the value inside a loop...
Extra commas are the new lack of semicolons!
