I don’t understand what I’m doing wrong when the answer comes up on the console.

Your code so far

def add_expense(expenses, amount, 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 = lambda x: x * 2
print(map(test, [2, 3, 5, 8]))
result = list(map(test, [2, 3, 5, 8]))
print(result)

# User Editable Region


expenses = []

Hi @zaccy

To obtain a readable output you need to turn the map object into a list. Do it by passing the map() call as the argument to the list() function.

You are not asked to define a new variable.

Happy coding
