minus-square@[email protected]linkfedilinkEnglish2•1 year agoI 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
minus-square@[email protected]linkfedilinkEnglish5•1 year agoWhat 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?
minus-square@[email protected]linkfedilink3•1 year ago What language do you use that accessing an object attribute is the same that accessing a dict key? Javascript / Typescript.
minus-square@[email protected]linkfedilinkEnglish3•1 year agoWell, yeah, I thought about later. Lua does the same. The other questions are still valid, though.
minus-square@[email protected]linkfedilinkEnglish1•1 year agoReturn undefined. Typescript. Why error? Just return undefined. Simple, no try/catch needed.
minus-square@[email protected]linkfedilinkEnglish1•1 year agoBecause that’s prone to errors. And the Zen of Python includes “explicit is better than implicit” and “Errors should never pass silently”. Languages that do otherwise create bad habits.
minus-square@[email protected]linkfedilinkEnglish0•1 year agoIs it? It’s just an optional property. And Typescript will tell you that it’s optional.
