Creating random number and appending to list

populate each hand with two cards. Take a card from the deck
and put it in the player_hand list. Then, take a card from the deck and
put it in the dealer_hand list. Do that one more time in that order so that the dealer and player have each two cards. Make sure the dealer’s first card is face down. I keep receiving this error from my 2 tests.

My code:

 while len(dealer_hand) != 2 and len(player_hand) != 2:
        player_card = random.choice(deck)
        player_hand.append(player_card)
        deck.remove(player_card)
        if len(player_hand) == 2:
            player_hand[0].face_up()
            player_hand[1].face_up()
        dealer_card = random.choice(deck)
        dealer_hand.append(dealer_card)
        deck.remove(dealer_card)
        if len(dealer_hand) == 2:
            dealer_hand[0].face_down()
            dealer_hand[1].face_up()

    return player_hand and dealer_hand


False != True

>Solution :

I think the error lies within the first line:

while len(dealer_hand) and len(player_hand) != 2:

If you want to check if the dealer also has 2 cards, you need to fix that line to:

while len(dealer_hand) != 2 and len(player_hand) != 2:
