the following codes are for the Hangman game. It gets a type error for the assignment display = list("_" * len(chosen_word)), saying that it is a Nonetype. Is this because chosen_word is not assigned (which is another error in itself)?. How can it be corrected? Any other suggestion to improve the code is also welcomed.

Following code worked perfectly,
JavaScript

str1 = ''.join(display)2
if str1 == chosen_word:3
guessed = True4
print("Congratulation, you won!")5
attempt=-16
I have just added above code and some minor changes in if-else conditions and some print statements. Remove extra print statements if you want!
