Python Blackjack game - referenced before assignment -


So, my personal challenge to make a simple Blackjack game Dragon this way I went about it : 

  singlePlayerCard = random.choice (availableCards) singlePlayerCard2 = random.choice (availableCards) if (singlePlayerCard == [1,2,3, 4,5,6,7,8,9 , 10]): singlePlayerCardValue = singlePlayerCard if (singlePlayerCard2 == [1,2,3,4,5,6,7,8,9,10]): singlePlayerCard2Value = singlePlayerCard2 singlePlayerCardValueTotal = singlePlayerCardValue + singlePlayerCard2Value print  < / pre> 
 when it comes to  print singlePlayerCardValueTotal  this tells me either (% singlePlayerCardValueTotal "your Ard Total% I values ​​") that  singlePlayerCalValue  or  singlePlayerCard2Value  has been referenced before assignment. This is a bit confusing as I have taken this issue with another simple program in the past, but the structure is different here. In addition to the above issue, it was working fine. If you have the time, please provide me a better solution for some areas if necessary. 
 
 As always, thanks in advance! After the text "itemprop =" text "> 
 if you have been told in your comment," referenced before work "means that

You have mentioned before that the value will be variable.

It seems that your problem is: 

  if (singleplayercard == [1,2,3,4,5,6, 7,8,9, 10]): singlePlayerCardValue = singlePlayerCard

your singlePlayerCard never in list equal to> [1 , 2,3,4,5,6,7,8,9,10] , you will not specify a value for a value when it is a number card.

== The operator is not a way to check whether the value is included in a list or not. Do ,: 

  if (singlePlayerCard [1,2,3,4,5,6,7,8,9,10]): singlePlayerCardValue = singlePlayerCard
