Tell us what’s happening:

I have already written the code right, and redid this a million times, but I can’t get ahead

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"]}')
    

# User Editable Region

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

# User Editable Region


expenses = []
