Answer:
The modified program is as follows:
user_input = input()
short_names = list(user_input.split(" "))
short_names.pop(0)
short_names[-1] = "Joe"
print(short_names)
Step-by-step explanation:
This gets the user input
user_input = input()
This converts input to list
short_names = list(user_input.split(" "))
This removes the first item of the list
short_names.pop(0)
This updates the last item to "Joe"
short_names[-1] = "Joe"
This prints the updated list
print(short_names)
