Hi. I just joined this forum because I really need some quick advice on a Blackjack game I'm working on. It's my first major endeavor, and I can't quite get it to work right. Here's the code.
#blackjack.py
from cards import *
from graphics import *
import random
DIM = 400
FILE = "blackjack.data"
BLACKJACK = 21
ACE = 1
ACE_HIGH = 11
CARD_X = 50
X_DIFF = 40
DLR_CARD_Y = 70
PLYR_CARD_Y = 340
def makeTable():
board = GraphWin("BlackJack!", DIM, DIM)
boardTop = Rectangle(Point(0,0), Point(DIM,DIM))
boardTop.setFill("green")
boardTop.draw(board)
quitbutton = Rectangle(Point(50,170), Point(120,220))
quitbutton.setFill("red")
quitbutton.draw(board)
quitText = Text(Point(85,195), "Quit")
quitText.setTextColor("black")
quitText.draw(board)
hitmeButton = Rectangle(Point(180,170), Point(250,220))
hitmeButton.setFill("blue")
hitmeButton.draw(board)
hitmeText = Text(Point(215,195), "Hit me")
hitmeText.setTextColor("white")
hitmeText.draw(board)
stayButton = Rectangle(Point(310,170), Point(380,220))
stayButton.setFill("yellow")
stayButton.draw(board)
stayText = Text(Point(345,195), "Stay")
stayText.setTextColor("black")
stayText.draw(board)
return board, quitbutton, hitmeButton, stayButton

I've been taught using the graphics.py class built by John Zelle (it came with a textbook). For some reason, the closeTable function always gets called when I run it.
I hope that the exclusion thing doesn't keep people from being able to answer. I can't in good conscience post the source codes for other classes without permission.
If you could offer some help, I'd appreciate it. Thanks!
