This ensures that the message is personalized for each friend.name.insert(0,'HBY')name.insert(3,'LQR')name.append('XFY')for friend in name:    message=f'welcome to the party, {friend}!'    print(message)# The new version of the code uses the insert() method to add new friends to specific positions in the list and the append() method to add a friend to the end of the list. The for loop then iterates through the updated list and prints a welcome message for each friend.print('Sorry, the party can only accommodate two guests.')while len(name) > 2:    removed_friend = name.pop()    message=f'sorry, {removed_friend}, you cannot attend the party.'    print(message)print('The party is now full.')# The new version of the code uses a while loop to remove friends from the list until only two guests remain. The pop() method is used to remove the last friend from the list, and a message is printed to inform them that they cannot attend the party. Finally, a message is printed to indicate that the party is now full.for friend in name:    message=f'welcome to the party, {friend}!'    print(message)# The new version of the code uses a for loop to iterate through the remaining friends in the list and print a welcome message for each of them.del name[0]del name[0]print(name)
