Insisnwrite unit tests, but they often passed for reasons other than the intended ones because of the dynamic typing. I kept adding tests every time I caught something runtime, but I was at an order of magnitude more tests than I would need with a strong and static types language. Pylance kept me from making thos mistakes in the first place.
