TypeError: init() missing 4 required positional arguments:

Question

This is my first program ever in Python, in fact in any language.

I get a TypeError and I am unable to solve it!

This is my code: (the error is below)

#! usr/bin/python
import time
import random

print("HI WELCOME TO HANGMAN !")
print("\n")
time.sleep(1.5)
name = input("Enter your name :")
print("\n")
print("HEY " + name + " HOPE YOU HAVE A GOOD TIME PLAYING HANGMAN TODAY")
print("\n")
time.sleep(1.5)
print("YOUR GAME IS ABOUT TO BEGIN IN A FEW SECONDS")
time.sleep(1)


class Hangman():
    def __init__(self, word, guesses, count, limit) :
        self.count = count
        self.display= "_" * self.length 
        self.word = word 
        self.length = len(word)

        words = ["book" ,"paper", "computer", "movie", "mouse", "laptop", "national"]
        self.word = random.choice(words)
    
    def play_loop(self):
        self.Continue = input("Do you wish to play another round? y = yes, n = no")
        if self.Continue == 'y':
            Hangman()
        elif self.Continue == "n":
            print("thanks for playing! hope you had a good time :)")
            exit()

    def play(self,guesses):
        self.count = 5
        print("your word is " + self.word + "enter your guesses ")
        self.guesses = guesses.strip()
        if len(guesses.strip()) == 0:
            print("Invalid input, please enter a letter \n")
        elif len(guesses.strip()) >=2:
            print("Invalid input, please enter one letter at a time \n")

        elif self.guesses in self.word :

            self.display = self.display[:self.index] + self.guesses + self.display[:self.index + 1]
            print(self.display + "\n")

        else:
            self.count +=1

        elif self.count == 3:

        elif self.count != self.limit:
            Hangman.play_loop()

Hangman_game = Hangman()
Hangman_game()

This is the error I get:

Traceback (most recent call last):
  File "/Users/angad/Desktop/hangman(no global).py", line 126, in <module>
    Hangman_game = Hangman()
TypeError: __init__() missing 4 required positional arguments: 'word', 'guesses', 'count', and 'limit'

Isn't the error message clear? The `__init__` method of your `Hangman` class requires 4 arguments (word, guesses, count, limit) but you are trying to instantiate it using `Hangman()` with no arguments. — Selcuk, Oct 26 '20 at 06:17
what should `Hangman_game()` accomplish? Why do you have a method for using a random word from a given wordlist and also provide a word to be guessed on initialization? Why do you print the word that needs to be guessed as plain text in your `play()` function? — Patrick Artner, Oct 26 '20 at 06:33
Tangentially, `usr/bin/python` tries to find `python` inside `bin` inside `usr` *in the current directory.* You need to add a slash to make it absolute `/usr/bin/python`; see perhaps also https://stackoverflow.com/questions/31435921/difference-between-and — tripleee, Oct 26 '20 at 06:44
patrick, self.count is actually the number of times a person guesses a wrong alphabet and thanks to that I found another mistake that I can correct.. thanks for the input on the self.word being in the __init__ and as a separate function, I have changed the code accordingly .... talking about the point why I print the word that needs to be guessed as plain text in play() function, are you talking about: print(self.display + "n")? — , Oct 26 '20 at 13:07
@ANGADSINGHBEDI Use ‘@’ to ping a previous commentator. Regarding the printing of the word that needs to be guessed, I guess they are talking about: `print("your word is " + self.word + "enter your guesses ")` — Brian Drake, Oct 26 '20 at 13:35
@ANGADSINGHBEDI `__init__()` sets `self.count`, but this value is never used, becuase the very first thing that `play()` does is to overwrite it. Why? — Brian Drake, Oct 26 '20 at 13:39
@BrianDrake thanks for that :)... yeah and about the self.count, I changed that, I removed a few initialisations and hope that the code is better.... i also changed the self.word to self.display so that should be fine now ....when I see another problem I am unable to solve, I will put it here:) — , Oct 26 '20 at 13:47

Look at Hangman class.

def __init__(self, word, guesses, count, limit) :

you need 4 arguments to initialize that class. Yet you did not put any when initializing.

Hangman_game = Hangman()
