main()I have to build a simple calculator that needs to read the command as a single line then it splits it up. but i also have to have a quit function but when I try and quit I get this error below.
builtins.ValueError: not enough values to unpack (expected 3, got 1)
also when the program quits it is supposed to print function usage statistics and end the program of course. But I am stuck on how to integrate how many times a function has been used before the user quits.
it should look something like this when it quits
Function usage count
add function: 1
sub function: 0
mul function: 2
div function: 0
abs function: 3
depending how many times the user used each function before quitting.
