I am trying to create a python program for my Casio fx-9750GIII calculator that computes the molar mass of a given chemical formula. To do this I need more methods for strings from curses.ascii such as isalpha. Unfortunately I don't know how modules work on a non-networked device. Do I just need to download a file and put it on the calculator for an import statement to work or is there something else I need to do?
As the commenter Lecdi said, it is a native python string method, I just made the mistake of typing isalpha() without a string beforehand.
