Need Help with Budget App

I’m very confused with tasks 17+ on the Budget App. I seem to be getting more or less the right answer, but I can’t get a pass, and I can’t figure out why None keeps printing. Any help would be greatly appreciated!!

Welcome to the forum @codfishhe,

Here’s an excerpt from the instructions:

You should have a function outside the Category class named create_spend_chart(categories) that takes a list of categories and returns a bar-chart string.

Is your function returning anything?

Happy coding

Welcome to the forum @codfishhe

The default behaviour of a function is to return None.

Do not use the print function to output text to the console.

Happy coding
