Build a Budget App Project - Build a Budget App Project

Tell us what’s happening:

Build A Budget App Project.
I can’t figure it out what’s wrong with my code in section create_spend_chart(categories). The output and the length of string are the same as the example.
Please help

Your code so far

class Category:
    def __init__(self, category):
        self.category = category
        self.ledger = []
        self.budget = 0

    def deposit(self, amount, description=''):
        self.budget += amount
        self.ledger.append({'amount': amount, 'description': description})

    def withdraw(self, amount, description=''):
        if self.check_funds(amount):
            self.deposit(-amount, description)
            return True
            return False

    def get_balance(self):
        return self.budget

    def check_funds(self, amount):

        if self.check_funds(amount):
            self.budget -= amount
                {'amount': -amount, 'description': f'Transfer to {another_category.category}'})
            another_category.deposit(amount, f'Transfer from {self.category}')

Hey, create_spend_chart should return a string. Once you return the string, you can open the console (F12) and see the difference between your output and the expected one:
The first line is yours, the second is the expected. You have extra spaces in one line and some "o"s are not in the right place.

I forgot to delete the spaces in the first line, but the other one I don’t get it, did I do something wrong with percentage calculation

Are you doing this?

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

thank you for your help, I recalculate the percentage and it works
