"Replace expected at least 2 arguments" – trying to write script for hangman game, need to replace letters with underscores

I need to replace the characters of a word with underscores for a hangman game. For example, "apple" would become "_ _ _ _ _". This is my code:

import random

chosen_word = random.choice(word_list)

for letter in chosen_word:
  str.replace(letter, "_ ")

The error message I’m receiving is

"File "main.py", line 17, in

str.replace(letter, "_")

TypeError: replace expected at least 2 arguments, got 1

As far as I can tell, there are two arguments. I’ve tried messing around with format and the arguments (letter, "_ "), but to be honest, I’m a total noob and have no idea what went wrong.

Thanks for reading.

>Solution :

In str.replace(), there is no string named str in your code.

import random

chosen_word = random.choice(word_list)

for letter in chosen_word:
  chosen_word = chosen_word.replace(letter, "_ ")
