Tell us what’s happening:

Describe your issue in detail here.
create_spend_chart should print a different chart representation. Check that all
spacing is exact.
The only x I got is this question. how to fix the problem? Please Help.

Your code so far

You appear to have created this post without editing the template. Please edit your post to Tell us what’s happening in your own words.
Learning to describe problems is hard, but it is an important part of learning how to code.
Also, the more you say, the more we can help!

I suspect it’s this:

The percentage spent should be calculated only with withdrawals and not with deposits.

It looks like you are totalling total deposits and calculating using that.

4

I think I’m only taking the withdrawals with this part of the code: if item[‘amount’] > 0

5

What is amount, is it a withdrawl?

Use this example and print out the variables you are using:

food = Category("Food")
food.deposit(1000, "deposit")
food.withdraw(10.15, "groceries")
food.withdraw(15.89, "restaurant and more food for dessert")
clothing = Category("Clothing")
food.transfer(50, clothing)
print(food)

print(create_spend_chart([food,clothing]))

Print your variables to troubleshot:

total_spent = sum(spent)
print("total spent", total_spent, spent)

Total withdrawls should be 76.04
