Hi, tests 17-24 are not passing. Although when checking and running the code, everything is fine and beautiful, it works with different amounts of spending and sums. What could be the problem?

Your code so far

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

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

    def withdraw(self,amount,description=''):
        if self.check_funds(amount):
            self.ledger.append({'amount': -amount, 'description': description})
            return True
        else:
            return False

    def get_balance(self):
        total = 0
        for elem in self.ledger:
            total+=elem['amount']
        return total

    def transfer(self,amount,destination):
        if self.check_funds(amount):
            self.ledger.append({'amount': -amount, 'description': f'Transfer to {destination.name}'})
            destination.ledger.append({'amount': amount, 'description': f'Transfer from {self.name}'})
            return True
        else:
            return False

    def check_funds(self, amount):
        if self.ledger[0]['amount']>=amount:
            return True
        else:
            return False

    def __str__(self):
        lines=[('*'*((30-len(self.name))//2))+self.name+('*'*((30-len(self.name))//2))]
        for obj in self.ledger:
            desc = obj['description'][:23]
            amo = '{:.2f}'.format(obj['amount'],2)
            lines.append(f"{desc.ljust(23)}{str(amo).rjust(7)}")
        lines.append(f'Total: {self.get_balance()}')
        return '\n'.join(lines)

    vsego_potrach = sum((-categories.ledger[1:][i]['amount'])   for i in range (len(categ)))

    znachen = {categ[i]:(-categories.ledger[1:][i]['amount']*100/vsego_potrach//10*10) for i in range(len(categ))}
    dlina_strok = len(categ)*3+1

    for i in range(100,-1,-10):
        stroka=(str(i)+'|').rjust(4)
        for key, elem in znachen.items():
            if elem>=i:
                stroka+=' o '
            else:
                stroka+='   '

    result = '\n'.join(gisto)
        
    return result

open the browser console

In there I see this error:

     for obj in categories.ledger[1:]:
                ^^^^^^^^^^^^^^^^^

 AttributeError: 'list' object has no attribute 'ledger'

you will need to fix that error
