Learn Lambda Functions by Building an Expense Tracker - Step 25

Tell us what’s happening:

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):
lambda expense: expense[‘amount’]

Sorry, your code does not pass.

You should create a lambda function that uses the parameter expense and returns expense[‘amount’] in your total_expenses function.

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):
        lambda expense: expense['amount']

# User Editable Region


expenses = []

for instance here:
lambda item: item[‘amount’]

Your code works from my end. Indentation may be the issue - if you reset you only need to change what is inside the function.

it worked after resetting. Thank you so much.
