> I die a little inside every time I see NameError or TypeError in a server log. Even Javascript can catch undefined variables before runtime (with use strict), but not Python. It's not like this is an accident, it's by design. Python pretty much waits until <<right now>> to bind things to names. It's part of the reason that it's "slow" and relatively challenging to make "fast." But OTOH you can do really interesting powerful stuff. "But I don't do that stuff"? Ok, maybe indeed Python's not for you. As a simple fix for this problem, vim users can use syntastic, atom users have a/several python plugins to check syntax, I'm sure VSCode and emacs have analogous plugins. Yes, their power is limited to only some kinds of checks, so TypeErrors can slip through.
