# Trying to solve the 'Arithmetic Formatter'

Tell us what’s happening:
Describe your issue in detail here.
Hey ! I’m new to python and I don’t understand why my code isn’t working with the tests that are made on replit.
I mean I know that there could be some errors but sometime in replit the expected output and my output are the same so I don’t get it…
Thanks if you can help and sorry for my poor level in Python
