My only problem lies in the create_spend_chard method or rather it representation. The test states that my output and the correct output are not the same. However, diff viewers does not see a difference:

Can you share your code or output or the devtools console error?
Nothing to go on here
Yeah sorry I failed to do so at the beginning and then my post was muted for some time because i wanted to post a link
Here’s the error message:

I’ve edited your code for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.
You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.
See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (').
Can you share your full code please?

Is that right? Because when I paste this code in I get this output:
<built-in method rstrip of str object at 0x10572b0>
and this console error:
AssertionError: '<built-in method rstrip of str object at 0x10b9db8>' != 'Percentage spent by category\n100| [383 chars] t '
I corrected it, sth went wrong when copy pasting, I’m sorry
When I use the example input:
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)
I don’t get the full chart as in the example, I only see this:
Transfer to Clothing -50.00
Total: 923.96
but the example says it should look like this:
*************Food*************
initial deposit 1000.00
groceries -10.15
restaurant and more foo -15.89
Transfer to Clothing -50.00
Total: 923.96
I checked with the code I posted and for me the category class works without problems. The only thing I’m wondering about is why it doesn’t accept the create_spend_chart method.
you have an issue with spaces, add this and see, the spaces in the output are replaced with dots. There is both your code and the expected one being printed.
food = Category("Food")
entertainment = Category("Entertainment")
business = Category("Business")
food.deposit(900, "deposit")
entertainment.deposit(900, "deposit")
business.deposit(900, "deposit")
food.withdraw(105.55)
entertainment.withdraw(33.40)
business.withdraw(10.99)
actual = create_spend_chart([business, food, entertainment])
expected = "Percentage spent by category\n100| \n 90| \n 80| \n 70| o \n 60| o \n 50| o \n 40| o \n 30| o \n 20| o o \n 10| o o \n 0| o o o \n ----------\n B F E \n u o n \n s o t \n i d e \n n r \n e t \n s a \n s i \n n \n m \n e \n n \n t "
print("actual" + "\n\n" + actual.replace(' ', '.') + '\n\n')
print("expected" + "\n\n" + expected.replace(' ', '.'))

Right, can see this in the diff now as well, I didn’t see it before for some reason
Thanks a lot! It worked
