Learn Lambda Functions by Building an Expense Tracker - Step 19

Tell us what’s happening:

The hint says i should pass the map function as the argument in the sum function.
My code does the exact thing but still can’t pass, why?

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

# User Editable Region


expenses = []
