one= ["one","number", "three", "hii"]
two = ["hi", "three hii"]

for x in range(len(one)):

    stuff =(one[x:])
    word = ' '.join(stuff)
    print(word)
    if word in two :
        one[x]= "yay" #updaates the list

HOW CAN I UPDATE THE LIST TO ONE = ["one","number","yay"] instead of one= ["one,"number","yay","hi"]?
