I have been working on a somewhat small Python GUI for a few weeks now primarily focusing on the GUI and not giving much in-depth thought to the logic of what is to be a simple card game. I assumed the logic to be in my head and in general it is but I am running into some problems I am having trouble solving.

Before I post some various code examples, I will tell you a bit of the trouble I am having: I have tried using both\ either dictionaries and lists to store card data; I see strengths and weaknesses in each for this program. I am not sure which would be the best at this point as I go back and forth trying different things and neither prove to be the winning answer. The trouble I believe lies in variable scope, specifically around the if\ elifs; there are many as there are 52 cards.

I have been working hard on this and I have tried many things but it seems when I think I solve one thing I have indeed tied myself up logically in another area locking myself into a corner it feels like. I think sometimes: "If I could just break out of the scope and access the nested variable from within." Yes, there is a way, I assume, but either I cannot recall it or do not know of it.

The game will be a basic "21" game. I have researched code and tried other's work but I felt initially I could make something better and do it all on my own. I need some personal assistance from someone knowledgable with this matter as I feel like I am going around and around.

I have learned some much though while doing this code and that is what really counts.

The actual problem reads like this: I wish to print 5 cards to the GUI screen. The Tkinter GUI work I need no help with--it is the logic at this point. I am missing something. I can print the first 5 cards to the screen easy enough but the code is hard-coded as it were and this is of no help-- I need it pseudo-random from a list or dictionary. OR, I run a random list or GUI which works fine but I am getting error messages such as:

This is the primary error I am contending with. I am so close to getting this to run beautifully I think. I have been doing hours of testing and editing, but keep coming back with the same or similar problems. Even when it runs it is just 5, set card defs printed to screen.

Any help, thoughts, directions, or hints will be greatly appreciated.

Looks like yo want to open a file called "50" even though the list is all integers.

Ene Uran is always of Great Help. He\ She should Moderate at DaniWeb!

Thank-you so much for your help and pointing out this simple solution to me, a glaringly obvious mistake I could not see. Sometimes it takes another person to look at something you've been staring at for hours\ days to see what you are missing.

Thanks again!

These are just general suggestions, but I hope they will be helpful rather than leading you down a wrong path.

(1) Creating a card class will solve a lot of problems for you. You can do something like this:

class Card(object):
  
  images = {0:"ace_spades.bmp", 1:"two_spades.bmp"} # etc.
  strings = {0:"AS", 1: "2S"} # etc.

  def __init__(self, value=None):
    if not value or value < 0 or value > 51:
      self.value = random.randint[0,51]
    else:
      self.value = value

  def __str__(self):
    return Card.strings[self.value]

  def display(self,canvas):
    # display self on the canvas using Card.images[self.value]

the Card.images value is now a class-wide constant, which I think takes care of the problem with variable scope.

(2) You can then create a Card.used_values list to keep track of already-dealt cards in the hand. You could perhaps modify the __init__ to look up the used_values and not deal any of those.

Hope it helps!
