Learn Lambda Functions by Building an Expense Tracker - Step 29

[Trevski]

Tell us what’s happening:

I am having trouble assigning the value of the input to the ‘choice’ variable but it seems like an error on freecodecamp’s site if I am not mistaken because in the next step, the solution to the previous step is seen which matches what I did in the previous step but it is still giving me an error. This is seen in steps 29, 31, 33, 35.

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')

        choice = input('Enter your choice:')

Hi there and welcome to our community!

@Trevski

choice = input('Enter your choice:')

This is correct except that there should be a space after the colon:

Inside your while loop, call the input() function passing the string 'Enter your choice: ' as the argument, and assign the result to a variable named choice .

Ohh, haha my eyes didn’t see that. I was spending so long wondering what was wrong with my code and it was just spacing all along.

Thank you so much for spotting that out!
