Dariusz,

You've declared ask_number() as an instance method in class Hand. You are calling it as if it was a class method. See https://docs.python.org/3.1/tutorial/classes.html.

Change your method:

def ask_number(self,question,low,high):    
        response=None
        while response not in range(low,high):
            response=int(input(question))


change  self to class:
This way you can call the method directly from Hand.

@classmethod
def ask_number(class,question,low,high):    
        response=None

In other words, you have to first create an instance of Hand before calling the ask_number method.

Your code might then be something like:
nr_players=Hand()
nr_players.ask_number("Ilu graczy ma wziąść udział w grze (2-5):",low=2,high=5)
