is there a way to make this shorter

maybe im just dumb but i cant seem to figure out how to make a calculator

Python

so many elif's i almost died while trying to read this

What language is that? (Looks like Python but I haven't studied it.) You should edit your post to include it after the opening backquotes for correct syntax highlighting, e.g. ```python

this is my solution, just did it quick so don't criticise it harshly lol

edit: tf forums screws up me putting it in a block so i put it in hastebin

edit: forgot to add verification to check that the function is of length 5 so if you want to copy and paste it be careful of that

okay, i guess its just me not being able to solve problems the simple way

is there a way to make this shorter
