--description--

You will need a function to calculate the total amount of expenses.

Define a function named total_expenses that takes one parameter expenses. Fill the function body with a pass statement for now.

--hints--

You should define a function named total_expenses.

js
({ test: () => assert(runPython(`
    import inspect    
    inspect.isfunction(total_expenses)
  `))
})

Your total_expenses function should take a single expenses parameter.

js
({ test: () => assert(runPython(`
    import inspect    
    sig = str(inspect.signature(total_expenses))
    sig == '(expenses)'
  `))
})

--seed--

--seed-contents--

py
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"]}')
