Wrong way

Test print_menu(. Should output the menu options. \[ \text { TypeError: print_menu() missing } 1 \text { required positional argument: 'customer_Cart' } \] Program errors displayed here Traceback (most recent call last): File "main.py", line 154 , in customer name = input ("Enter customer's name: " ) EOFError: EOF when reading a line argument, which is customer_Cart. This means that when you call the print_menu fu need to provide an argument for customer_Cart. Here's how you could fix the issue: \( \begin{array}{ll}1 & \text { def print_menu(newCart): } \\ 2 & \text { customer_Cart }=\text { newCart } \\ 3 & \text { } \\ 4 & \\ 5 & \# \text { Call the function and provide an argument } \\ 6 & \text { cart = ShoppingCart(customer_name="Customer", current_date="February 12, 2023") } \\ 7 & \text { print_menu(cart) } \\ 8 & \end{array} \)
