Tell us what’s happening:
In the total_expenses function, you’ll now integrate a lambda function. Replace pass with a lambda function that has expense as its parameter.
expense is expected to be a dictionary, and your lambda function should return the value of the ‘amount’ key in the expense dictionary.
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):
return sum(map(lambda expense: expense['amount'], expenses))
# User Editable Region
expenses = []
