Mine is the python debugger. I was a long holdout thinking that print statements were sufficient. That was untill I started having errors crop up in functions that took minutes to run. The thing that I most notably wish I would have known about is post_mortem.
Example
[ins] In [4]: def repeater(msg, repeats=1):
...: "repeats messages {repeats} number of times"
...: print(f'{msg}\n' * repeats)
[ins] In [5]: repeater('hi', 3)
hi
hi
hi
[ins] In [6]: repeater('hi', 'a')
