minus-square@[email protected]linkfedilinkEnglish2•2 years 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-squarerichieadler 🇦🇷linkfedilinkEnglish4•2 years 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@Hallainzillink2•2 years ago What language do you use that accessing an object attribute is the same that accessing a dict key? Javascript / Typescript.
minus-squarerichieadler 🇦🇷linkfedilinkEnglish3•2 years agoWell, yeah, I thought about later. Lua does the same. The other questions are still valid, though.
minus-square@[email protected]linkfedilinkEnglish0•2 years agoReturn undefined. Typescript. Why error? Just return undefined. Simple, no try/catch needed.
minus-squarerichieadler 🇦🇷linkfedilinkEnglish1•2 years 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•2 years agoIs it? It’s just an optional property. And Typescript will tell you that it’s optional.
