Tell us what’s happening:

I can’t pass the last test. I tried with several options, and even replaced all the white space with tildes to make sure my spacing was correct. I’ve removed the final white line, so that isn’t it. I don’t understand the debugger, I don’t see how I can replicate the mistake it’s apparently making. Please help!

Your code so far

            self.ledger.append({'amount': -amount, 'description': description})

Welcome to the forum @LiLuStitch!

I tested using these transactions and function call:

    categories = []
    food = Category('Food')
    categories.append(food)
    food.deposit(1000,'deposit')
    food.withdraw(10.15,'groceries')
    food.withdraw(15.89,'restaurant and more food for dessert')
    clothing = Category('Clothing')
    categories.append(clothing)
    food.transfer(50, clothing)
    clothing.deposit(800,'deposit')
    clothing.withdraw(55.20,'jacket')
    auto = Category('Auto')
    categories.append(auto)
    auto.deposit(500,'deposit')
    auto.withdraw(42.39,'fuel')
    auto.withdraw(78.62,'oil change')
    for cat in categories:
        print(cat)
    print(create_spend_chart(categories))

Your code print this chart:

Percentage spent by category
100|       o  
 90|       o  
 80|       o  
 70| o     o  
 60| o     o  
 50| o  o  o  
 40| o  o  o  
 30| o  o  o  
 20| o  o  o  
 10| o  o  o  
  0| o  o  o  
    ----------
     F  C  A  
     o  l  u  
     o  o  t  
     d  t  o  
        h     
        i     
        n     
        g

But it should print this chart instead:

Percentage spent by category
100|          
 90|          
 80|          
 70|          
 60|          
 50|       o  
 40|       o  
 30|       o  
 20| o  o  o  
 10| o  o  o  
  0| o  o  o  
    ----------
     F  C  A  
     o  l  u  
     o  o  t  
     d  t  o  
        h     
        i     
        n     
        g

So, it looks like there is something wrong with the way you are calculating withdrawal percentages.

If you open your browser’s console, you can see more information about the error. It’s a bit cryptic, but basically the - indicates your code’s output and the + indicates what the test expects.

Happy coding!

Thank you so much, I figured it out! I made a typo in my percentage calculations and I rounded regularly instead of down to the nearest 10. That did it :smile:
