Tell us what’s happening:
The code works perfectly fine and the outputs match exactly (from what I can tell) what it’s asking for, yet no matter what, I’m still getting the same two failures from freecodecamp saying:
“Failed: Printing a Category instance should give a different string representation of the object.
Failed: create_spend_chart should print a different chart representation. Check that all spacing is exact.”
Anyone have any ideas on how to fix it? I have also tried calling and not calling the functions. Many thanks!
Your code so far
