how can I be able to input text instead of numbers (python)?

I’m making a simple program, but after inputting, there is always a ‘ValueError: invalid literal for int() with base 10’ after I try to put in a word. Basically, this program is supposed to make you type in a 3 letter word, but whenever I try and put in a word, there’s only an error message.

words = []
game = "play"
while game == "play":
    new = input("write something with 3 letters: ")
    if len(new) > 3 or len(new) < 3:
        print("That's not a 3 letter word.")
        
    else:
        if new in words:
            game = "over"
            print("you already said that word. Game over.")
            print("You know len(words), 3 letter words.")
else:
                print("u win")
                
                words.append(new)

did I do anything wrong? the problem seems to be in line 4???

>Solution :

I think I know whats going wrong 🙂

words = []
game = "play"
    while game == "play":
    new = input("write something with 3 letters: ")
    if len(new) > 3 or len(new) < 3:
        print("That's not a 3 letter word.")
    
    else:
        if new in words:
            game = "over"
            print("you already said that word. Game over.")
            print("You know len(words), 3 letter words.")
        else: # <---- you forgot a few tabs here ;)
            print("u win")
            words.append(new) # <---- this part is important

you never appended the new words to the list.
