Build a Budget App - Build a Budget App

Tell us what’s happening:

I know this is a little early but why isn’t test case 6 getting checked off? It does exactly what it’s supposed to do? And also, what does it mean for example in test case 1 where it says that the deposit method should create a specific object in the ledger instance variable? Am I not appending an object into the ledger instance variable? These two things would really help me to continue.

Your code so far

current_balance = 0

class Category:
    def __init__(self, name):
        self.name = name
        self.ledger = []

    

    def deposit(self, amount, description = ""):
        self.ledger.append(f"amount: {amount}")
        self.ledger.append(f"description: {description}")


    def withdraw(self,amount, description= ""):
        global current_balance
        #loops through the ledger list
        for i in self.ledger:
            #looks for the amount deposited
            if "amount" in i:
                #converts that amount to an integer
                conversion = int(i[8:])
                #Checks to see if withdrawal amount is possible
                if amount <= conversion:
                    self.ledger.append(f"amount: -{amount}")
                    self.ledger.append(f"description: {description}")
                    current_balance = conversion - amount
                    return True
                    
                else:
                    return False

    def __str__(self):
        return str(current_balance)


def create_spend_chart(categories):
    pass

food = Category("food")
food.deposit(900, 'deposit')
print(food.withdraw(45.67, 'milk, cereal, eggs, bacon, bread'))
print(food)

Hi @justinnyakundi232

The class needs to handle the balance, so you cannot use global variables.

Happy coding

Oh ok, but using the same code why doesn’t test case 2 work? I set the default value of the description to a blank string if none is inputted.

Don’t use the tests to code. Keep implementing the instructions until the app is working fully. Then run the tests to see if anything needs to be fixed.

Run your own tests by calling the function.
