I am trying to input [1] and enter a new word to append the  existing words at list '''words''' in shuffle pattern.
import random
words = ['apple', 'banana', 'orange', 'coconut', 'strawberry', 'lime']
old_word = []
while True:
    choice = int(input('Press [1] to continue [2] to exit: '))
    if choice == 2:
        break
    
    elif choice == 1:
        new_word = input('Enter a new word: ')
        old_word.append(new_word)
        words.append(old_word)
        if new_word in words:
            random.shuffle(words)
            print(words)
e.g
input 1
Enter a new word: lemon 
output  'orange', 'banana', 'lime', 'apple', 'lemon','coconut', 'strawberry'
