Python 3.3 Button hiding coding doesnt work - button

Question

In my game after pressing the start button I wanted to hide the button to stop the user from pressing the start button again and making more bubbles appear. I tried to make a variable equal to 0. Then every time the start button was clicked the value would go up by 1. If the value was 2 then the start button would disappear or become inactive. By trying to add this 'hiding button code' its only showing one bubble on my screen when the start button is clicked. Oh and the started button doesn't hide... ._.
from tkinter import *

self.name = name
root.title("Math Bubbles")
self.bubbles = {} # this will hold bubbles ids, positions and velocities
self.score = 0
self.buttonclick = 0 # Newly added in attempt to hide button
Button(root, text="Start", width=8, bg="Pink", command=self.make_bubbles).pack() # This button starts the game, making the bubbles move across the screen
Button(root, text="Quit", width=8, bg="Yellow",command=quit).pack()

I faced IndentationError in line 103 and NameError in 39 (it is self.buttonclick not buttonclick). Next time check your code before posting.
Well, you invoke 20 buttonclicks each time you click on Start button and the value checking happens in the middle of the process.
I fixed the make_bubbles method for you abit.
def make_bubbles(self):
self.buttonclick += 1 #Newly added in attempt to hide button
if self.buttonclick == 2: #Newly added in attempt to hide button
self.startbutton.configure(state="disabled")
showinfo("Oh No", "Sorry %s, but the game is already started" % self.name)
return
for each_no in range(1, 21):
...
The logic to enable the button at the end of game is missing or perhaps no need at all. Maybe I would rather clear all bubbles and generate 20 new ones each time I click the Start button. Anyway, I recommend this site for tkinter programming.
There is some more things to fix here too. No more iteritems() in Python 3. Use self.bubbles.items() instead. Good luck!
