Here's my code, when I delete one argument it works, but with four, it gave me this mistake.
class Monster:
def __init__(self, hit_point, weapon, color, sound):
self.hit_point = hit_point
self.weapon = weapon
self.color = color
self.sound = sound
>>> from monster import Monster
>>> a = Monster(5, 'sword', 'blue', 'roar')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

I have just run your code without any errors. Check you indentation in the init method. This is my code, the str method just prints out the attributes of the class in a more readable format.
class Monster:
def __init__(self, hit_point, weapon, color, sound):
self.hit_point = hit_point
self.weapon = weapon
self.color = color
self.sound = sound
def __str__(self):
return "{} {} {} {}".format(self.hit_point,self.weapon,self.color,self.sound)
from monster import Monster
a = Monster(5, 'sword', 'blue', 'roar')
print(a)
hope this helps !
