To show the total expenses, create an elif statement that checks if choice == '3'.
If it's true, it means the user wants to see the total expenses. So call print() and pass the string '\nTotal Expenses: ' as the first argument and total_expenses(expenses) as the second argument.
You should create an elif clause that checks if choice == '3'.
({ test: () => assert(runPython(`
cond = _Node(_code).find_function("main").find_whiles()[0].find_bodies()[0].find_ifs()[0].find_conditions()[2]
cond.is_equivalent("choice == '3'") or cond.is_equivalent("'3' == choice")
`)) })
You should print '\nTotal Expenses: ', total_expenses(expenses) in your new elif clause.
({ test: () => assert(runPython(`_Node(_code).find_function("main").find_whiles()[0].find_bodies()[0].find_ifs()[0].find_bodies()[2].has_call("print('\\\\nTotal Expenses: ', total_expenses(expenses))")`)) })
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)
