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

for x in range(len(one)):

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

i want to be able to do the for loop again if the list one has changed otherwise i dont want it to do anything
