Learn Lambda Functions by Building an Expense Tracker - Step 21

Tell us what’s happening:

I am not sure what I have done wrong. I called the map function in the test variable and also in print. I am not sure what else to do

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):
    pass
    

# User Editable Region

test = map(lambda x: x * 2, [2, 3, 5, 8])
print(map(test([2, 3, 5, 8])))

# User Editable Region


expenses = []
