Please explain the method of inserting an item at a specific position in the list

Question

def addtolist(newitem):
    showlist()
    if len(shoppinglist):
        position = input("Where should I add {}
"
                         "Press Enter to add to end of the list
"
                         ">".format(newitem))
    else:
        position = 0
    try:
        position = abs(int(position))
    except ValueError:
        position = None
    if position is not None:
        shoppinglist.insert(position-1, newitem)
    else:
        shoppinglist.append(newitem)
    show_list()
In the if-else statement in the above function, if we set the position =0,when there are no items in the list, how the item will be added to the list using the statement:
 shoppinglist.insert(position-1, newitem)..
Won't it make the position negative again!!
Please exlplain
