Python

Tell us what’s happening:

You should pass the map() call as the argument to the list() function.

Any one can help please!

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

# User Editable Region


expenses = []

hi @Atrox

It is great that you solved the challenge, but instead of posting your full working solution, it is best to stay focused on answering the original poster’s question(s) and help guide them with hints and suggestions to solve their own issues with the challenge.

We are trying to cut back on the number of spoiler solutions found on the forum and instead focus on helping other campers with their questions and definitely not posting full working solutions.
