python – Secrets: removing generated variables from a previously defined list?

Firstly thank you so much for taking the time to help.

I’m using secrets to give me two random variables from a previously defined list. I need to do this twice in succession. The second time, I need the programme to select from the same list, except without the possibility of selecting the two that were returned in the first instance.

num_to_select = 2
unassigned_cards = (2,3,4,5,6,7,8,9,10,10,10,10,'ACE')
draw_cards = 4*unassigned_cards
dealers_cards = secure_random.sample(draw_cards, num_to_select)
players_cards = secure_random.sample(draw_cards, num_to_select)

This error message appears, understandably, because I’ve asked it to remove objects that are not present in the original list.

ValueError                                Traceback (most recent call last)
<ipython-input-2-0d34b9c572c9> in <module>
      1 dealers_cards = secure_random.sample(draw_cards, num_to_select)
----> 2 draw_cards.remove(dealers_cards)()
      3 players_cards = secure_random.sample(draw_cards, num_to_select)
      5 print('Dealer drew', dealers_cards,'for a total of', sum(dealers_cards))

ValueError: list.remove(x): x not in list

For clarification, this is for a game of playing cards, so I multiplied the list by 4 in the third line of code to represent four suits, so removing the “dealer’s cards” from the list should only reduce the likelihood of drawing a particular number, not make it completely impossible.

Please explain where I’ve gone wrong here.
