Learn Lambda Functions by Building an Expense Tracker - Step 30

Tell us what’s happening:

I can’t figure out how to get my code to pass beyond this point. I need to declare a variable named amount and assign it to an empty input() call within an if statement.

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))
    
def filter_expenses_by_category(expenses, category):
    return filter(lambda expense: expense['category'] == category, expenses)

def main():
    expenses = []
    while True:
        print('\nExpense Tracker')
        print('1. Add an expense')
        print('2. List all expenses')
        print('3. Show total expenses')
        print('4. Filter expenses by category')
        print('5. Exit')
        if choice == '1':
            amount == input()
        choice = input('Enter your choice: ')

under the choice variable

A small detail but… still important! You need to assign the variable before you can check it
