I need help understanding a program structure using classes

[CompleteNewb]

Please run this and see if it helps you understand whyhandandself.handare two different things.

class Player:
	flop = []
	turn = []
	river = ['This is Player.river']
	 
	def __init__(self, number, chips):
		self.number = number
		self.chips = chips
		self.hand = ['This is self.hand']
		self.show_how_to_use_class_and_local_variables ()

	def show_how_to_use_class_and_local_variables (self) :
		print ('\n')
		print (self.hand)
		print (Player.river)
		print ('Next is the error because "hand" is undefined.\n\n')
		print (hand)

player1 = Player (7, 11)

Okay but jsut a couple more things:

hand = 3#(1)<---------------I can have a global variable with the same name has an instance variable
deck = [['1','H'], ['2','H'], ['3','H'], ['4','H'], ['5','H']]

def pickacard(deck):
    card = deck[0]
    deck.remove(deck[0])
    return card

class Player:
    flop = []
    turn = []
    river = ['This is Player.river']
      
    def __init__(self, number, chips):
        self.number = number #(2)<---------Since it's number I need to pass an argument when I create an object of that class
        chips = 4#(3)<----------------Since there's no self. before this doesn't work
        self.hand = []#(4)<------------Since i declare it has an empty list, I don't need to give an argument when i create an object, but how do append something do this list?
        self.show_how_to_use_class_and_local_variables ()
 
    def show_how_to_use_class_and_local_variables (self) :
        print ('\n')
        print (self.hand)
        print (Player.river)
        print ('Next is the error because "hand" is undefined.\n\n')
        print (hand)#<----------------This calls the global variable, not the instance variable
        #print(self.chips)#(5)Doesn't work because you can't declare a instance variable like this


    def pickplayershand(self, deck, pickacard):  #<--------- Here (6)
        card = pickacard(deck)
        deck.remove(deck[0])
        hand.append(card)#<--------------------And here(7)
        card = pickacard(deck)
        deck.remove(deck[0])
        hand.append(card)
        return


player1 = Player (7, 11)
print(player1.hand)

How can I modifie self.hand? (4)
#(6) How do i pass the instance variable hand as an argument? self.hand or Player.hand?
#(7)How do I append something to an instance variable list ? Do I write self.hand.append(card)???? (it doesn't work...)
