I need help understanding a program structure using classes

[CompleteNewb]

We can't run your code becausestraightfunction,pairfunctionandflushfunctionare missing but I can help you understand why the variablehandis throwing the error that you're getting.
Variables defined in a class before the__init__method are called "class variables". They are called that because they are shared by every instance of that class. In the code below I show you how to set a class variable but more importantly, why you shouldn't try to use them the way that you are. The reason for this is becausePlayer.handis the same for bothplayer_oneandplayer_two.

class Player :
	hand = []
	def __init__ (self, number, chips) :
		self.number = number
		self.chips = chips

player_one = Player (7, 11)
player_two = Player (7, 13)

Player.hand = [['1', 'H'],['2', 'D'],['3', 'C'],['4', 'S']]

print (f'Hand for player one is {one.hand}.')
print (f'Hand for player two is {two.hand}.')

Thanks for answering back. I really appreciate it. So i put them in the constructor? But what about the flop? Do i put the flop, turn and river as class variables and change it at every turn, because I can't pass variable as a argument in a function called inside a function inside a class?
