Tell us what’s happening:
keeps telling men to print_expenses() before expenses_form_ category…indetation is off, wont let me tab or space half the time…makes not sense…
Your code so far
… Sorry, your code does not pass. Keep trying.
- Your
print_expenses()call should come after theexpenses_from_categoryvariable.
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: ')
if choice == '1':
amount = float(input('Enter amount: '))
category = input('Enter category: ')
add_expense(expenses, amount, category)
elif choice == '2':
print('\nAll Expenses:')
print_expenses(expenses)
elif choice == '3':
print('\nTotal Expenses: ', total_expenses(expenses))
