Hi team. I think a space is preventing my code from passing. Please help.

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 = []

You should return sum(map(lambda expense: expense['amount'], expenses)) from your total_expenses function.

Your function doesn’t return anything
