minus-squarecocobean@bookwormstory.sociallinkfedilinkEnglisharrow-up2·1 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-squarerichieadler@lemmy.myserv.onelinkfedilinkEnglisharrow-up5·1 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-squareHallainzil@lemmy.worldlinkfedilinkarrow-up3·1 year ago What language do you use that accessing an object attribute is the same that accessing a dict key? Javascript / Typescript.
minus-squarerichieadler@lemmy.myserv.onelinkfedilinkEnglisharrow-up3·1 year agoWell, yeah, I thought about later. Lua does the same. The other questions are still valid, though.
