Tell us what’s happening:

This is my second attempt im not sure what to do next

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 = lambda x: x * 2

map_object = map(test, [2, 3, 5 8])

result_list(map_object)

print(result_list)

# User Editable Region


expenses = []

@shamarbrowne you attempt is nice. lets work together to find a solution to this step.
delete the below lines of code we want to keep thing simple.

Step 14

You should see something like <map object at 0xd273a8> printed on the console, which is the string representation of the map object returned by map().

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.

test = lambda x: x * 2

print(map(test, [2, 3, 5, 8])) if you look at this print call you will see a map object in a map () function which is map(test, [2, 3, 5, 8]) . so the step requires that you turn this map object into a list by passing it as an argument to list() then put everything back into the print() function call. try this and let us know.
