Having problems with freeCodeCamp coding environment for Build a Budget App

Programming Python

Hey, I completed this on my local vs studio and pasted it into the web browser but it didn’t want to work even though it works fine locally.

class Category:

            self.ledger.append({'amount':-amount, 'description': description})
            return True
        else:
            return False
        

    def get_balance(self):
        balance = 0
        for i in range(len(self.ledger)):
            balance += self.ledger[i]['amount']

        return balance

    def transfer(self, amount, destination):
        if self.check_funds(amount):
            self.withdraw(amount, f'Transfer to {destination.name}')
            destination.deposit(amount, f'Transfer from {self.name}')

def create_spend_chart(categories):
    total_spent_per_category = {}

print(create_spend_chart([food, clothing]))

Here is the local output that get’s printed to the terminal:

Here’s what the browser one for freeCodeCamp outputs:

Hey @dawidbenjamincoetzee,

I see that same error in the terminal when I run your code in VSCode, so this has nothing to do with the fCC editor.

Suggest you focus on the error rather than the environment.

Happy coding

I don’t understand it works fine on my vs code

final_output = f'{stars_left * '*'}{self.name}{stars_right * '*'}'

You used single quotes ' for the f-string.

And also inside'*' , it closes the string early.

So the parser thinks the expression is broken.

You can use double quotes ” for the f-string.

Please check all f-strings.
