Tell us what’s happening:

why its give a mistake in total_expenses function? i think all right, Step 25 - lambda function

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 = []

here a mistake

Sorry, your code does not pass. Hang in there.

You should create a lambda function that uses the parameter expense and returns expense['amount'] in your total_expenses function.

you need to create the lambda function, you did more than that and the tests don’t pass. You need to only create the lambda
