Tell us what’s happening:

why is it telling me that map() must have at least 2 arguments and I thought I did have 2 arguments so what did I do wrong?

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 = []
