Can’t quite figure out why my code isn’t passing still. I’ve tried everything already posted on the forum but it’s still not working

Your code so far

def add_expense(expenses, amount, category):
    expenses.append({'amount': amount, 'category': category})
    
def print_expenses(expenses):
    for expense in expenses:
        print(f'Amount: {expense["amount"]}, Category: {expense["category"]}')

def total_expenses(expenses):
    sum(map(lambda expense: expense['amount'], expenses))
    return total_expenses
