We need to see your code to help you.
There are two ways you can format your code to make it easier to read and test:
- After you copy/paste your code into the editor, select it by dragging your cursor over it then click the (
</>) button in the toolbar to automatically wrap your code in backticks. (You can click on the animated demo image below to enlarge it.)
- Manually add three backticks on a new line above your code and on a new line after your code. Note that a backtick is NOT the same as a single quote('). To find the backtick key on your keyboard, see this post.
To see changes to your post as you make them, you can click the (M+) button on the toolbar to bring up the rich text editor:

Test your code:
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]))
What do you see in the fCC editor’s console pane?
Were you asked to create a class variable?
No, I wasn’t, however the class variable helped me to develop the code.
As for the result in the console pane, I’ll be giving you some feedback tomorrow.
Thank you.
You shouldn’t need it since you are expected to pass an array of category instances to the create_spend_chart function, and I’m not sure the tests will support that.
All I see in the console output is the string representation of the ‘food’ object. There is no output of the spend chart. And not a single test passes now.
Please share your updated code so we can take a look.
I just added
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(\[food,clothing\]))
after my code in the editor to test it, as you suggested. Apart from that, I made no changes.
Did you see this type error in the console?
Traceback (most recent call last):
File "main.py", line 149, in <module>
File "main.py", line 106, in create_spend_chart
TypeError: object of type 'Category' has no len()
I can see it now, yes. Definitely.
Hi,
I did some debugging. Now, the tests keep running and running, without end.
Once, I got an error message in the console:
Error: Timed out waiting for the test worker to initialize
But each attempt to “Check your code” results in the tests running infinitely.
please post your code so we can check if it’s an issue with that
