Python, and I like that I know it

I had to use Python for a bit at work and it was confusing

pipenv, venv, virtualenv, poetry...wtf is all this shit

a.b vs a['b'] vs a.get('b')...wtf is a KeyError

What happens in other languages you use when you try to access a non-existing key for a hash/map/dict?

What language do you use that accessing an object attribute is the same that accessing a dict key?

What knowledge do you have (or not) that KeyError is a mistery to you?

Typescript.

Is it? It's just an optional property. And Typescript will tell you that it's optional.

For me I really appreciate that doing anything in Python is trivial. Want to do scripting? Sure. Want to do http requests? Why not.

The only thing I'd say is difficult is making a UI. In those cases you're sometimes better off using django
