Python script

[sciencebear]

This is a script I wrote back in my first week of python for a one-dimensional game of life. It worked that first week, but I'm not sure the indents are still right. It gives me an error that self is not defined after the user says what cells are on to being with.

 

from Tkinter import *

#WORLD CREATION
numcells = input("How big is the world? ")
world = [0 for i in range(numcells)]

w = 800/numcells
h = 25

#RULES CREATION
#0 for off, 1 for on
#Prompts user with all permutations
print "What will happen to the center? "
rules = [0 for i in range(]
rules[0] = input("0 0 0 -> ")
rules[1] = input("0 0 1 -> ")
rules[2] = input("0 1 0 -> ")
rules[3] = input("0 1 1 -> ")
rules[4] = input("1 0 0 -> ")
rules[5] = input("1 0 1 -> ")
rules[6] = input("1 1 0 -> ")
rules[7] = input("1 1 1 -> ")

#START STATE
print "Which cells are on? Give -1 to stop."
index = input("CELL #")
while index <> -1:
  world[index-1] = 1
  index = input("CELL #")

prevworld = [0 for i in range(numcells)]

def nextworld():
  for i in range(numcells):
    c = i
    l = i-1
    r = i+1
    if l < 0:
      l = numcells-1
    if r == numcells:
      r = 0
    rule = 4*prevworld[l]+2*prevworld[c]+prevworld[r]
    world[c] = rules[rule]
  return world

class TkAutomaton:

        self.tk = Tk()
        self.tk.wm_geometry("800x600+20+40")

        self.canvas.pack()

for i in range(numcells):

  y1 = 0
  x2 = (i+1)*w

    self.canvas.create_rectangle(x1, y1, x2, y2, fill="red", outline="red")

    self.canvas.create_rectangle(x1, y1, x2, y2, fill="blue", outline="blue")
    prevworld[i] = world[i]
    self.iter = 0
    self.tk.update()


#    def moveSquareUp(self, s):
#        self.canvas.move(s, 0, -50)

    def finish(self, e):
      self.done = 1

    def step(self, e):
      self.go = 1

    def update(self):
# put your update code here
      if self.go:
        self.iter = self.iter + 1
        wor = nextworld()
      for i in range(numcells):
        x1 = i*w
        y1 = self.iter*h
        x2 = (i+1)*w
        y2 = (self.iter+1)*h
      if wor[i] == 1:
        self.canvas.create_rectangle(x1, y1, x2, y2, fill="red", outline="red")
      elif wor[i] == 0:
        self.canvas.create_rectangle(x1, y1, x2, y2, fill="blue", outline="blue")
      prevworld[i] = wor[i]
    self.go = 0
  self.tk.update()


a = TkAutomaton()

while not a.done:
    a.update()

 

Anyone know what is going on?

Can you give the full error please?

 

Is the for loop meant to be in the TKAutomaton Class?

If so then it isn't indented right.
