Tell us what’s happening:
I think there is a problem in how Step 19/20 are stated. Both steps want to utilized a key from the ‘expense’ dictionary, but the only defined dictionary in the code is ‘expenses’, but I can only get the solution by using ‘expense’.
Am I missing something or is this an error that needs to be corrected?
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):
return sum(map(lambda expense: expense['amount'], expenses))
# User Editable Region
def filter_expenses_by_category(expenses, category):
lambda
# User Editable Region
expenses = []
