Starting off a Tic Tac Toe game in Pythonista, but I can't quite figure out how to get the computer to randomly pick a button then draw the image. Any help?

# coding: utf-8

import ui
import random

global buttons
buttons = ['button1', 'button2', 'button3', 'button4', 'button5', 'button6', 'button7', 'button8','button9']

def computer_pick():
    global buttons
    computer = random.choice(buttons)
    name = 'name: %s' % computer
    computer = ui.Button(name)
    computer.image = ui.Image.named('ionicons-ios7-circle-outline-32')

def button_tapped(sender):
    global buttons
    sender.image = ui.Image.named('ionicons-close-32')
    buttons.remove(sender.name)
    print buttons
    computer_pick()

v = ui.load_view('tic-tac-toe')
v.present('sheet')

I just want help with this, I'd like to figure the rest out on my own :)

Do those buttons already exist in the view?
ui.Button(name) is creating a new instance. I think you want to send sender to computer_pick, and use
computer = sender.superview[name]

Tried this and doesn't work.

sender gets only what the user pressed

The point is, you need to get to the view containing the buttons. Sender presumably is a subview of your root view, so the superview is the view containing all buttons. But Not having your pyui, I'm guessing. So passing sender as an argument to computer_ pick should let you select the appropriate subview. You could also just pass sender.superview, or have that be a global, given that you are using globals anyway. ( you might later consider putting globals in a class so they are not actually global, but constrained to a class instance). The point is, the computer pick function needs to know where to find the actual button instances.

Unbeatable tictactoe was a bit more complicated than I thought it would be...

Please let me know if you can win against it.
