InPYTHONplease create a program for the following:

Your friend Susie has a problem. She goes grocery shopping on a weekly basis, and always seems to forget to buy items that she needs. You have suggested that she make a list before she goes, and have offered to write a program to help Susie produce her list.

The program should define at least 2 functions to help perform the above tasks:

addItem(alist)

The function addItem accepts one parameter, which is a list. This function prompts the user for an item to be added to the list. If the item is not already on the list, the item is added to the end of the list. Otherwise, a message is given indicating that the item is already on the list.

removeItem(alist)

The function addItem accepts one parameter, which is a list. This function prompts the user for an item to be removed from the list. If the item on the list, it is removed from the list. Otherwise, a message is given indicating that the item was not on the list.

printOut(alist)

The function printOut accepts one parameter, which is a list. This function prints out a header: GROCERY LIST followed by a list of all of the items in the list, one at a time.

The main part of your program will start by creating an empty list. The user will then be allowed to choose any of the following UNTIL he/she wishes to exit.
