Tell us what’s happening:
Hi
i was try to do the # 19 Lambda Functions , but the app tell me
You should call the sum() function passing it your current map() call as the argument and return the result from your total_expenses function.
and my code it’s
def total_expenses(expenses):
sum(map(lambda expense: expense[‘amount’], expenses))
return total_expenses
i don’t know whats 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"]}')
# User Editable Region
def total_expenses(expenses):
sum(map(lambda expense: expense['amount'], expenses))
return total_expenses
# User Editable Region
expenses = []
