Python Simon Game: I Got Stuck Finishing the Sequence
<p>I'm finally finishing my Simon Game, but I have some doubts about how to complete the sequence.</p>

<p>Edit: As you asked I have edited my post. Here I will post my code as it was before this post. So here are my actual problems.</p>

<p>1) I don't know how to add one number to the sequence after each turn.</p>

<p>2) The first turn works fine, but I don't know how to start the next turn, I've tried to call again the function after checking the sequence but it doesn't worked.</p>

<p>The necessary code for the two things:</p>

<pre><code>from Tkinter import *
import Tkinter
import random

base = Tkinter.Tk()

fr = Tkinter.Frame(base, bg='black', width='238', height='250')

score = Tkinter.Label(base, bg='black', fg='white', text='Score:')
score.place(x = 30, y = 15)

s = 0

scoreNum = Tkinter.Label(base, bg='black', fg='white', text = s)
scoreNum.place(x = 70, y = 15)

clicks = []
color = 0

def yellowClick():

    yellow.configure(activebackground='yellow3')
    yellow.after(500, lambda: yellow.configure(activebackground='yellow'))

    global clicks
    global color

    color = 1
    clicks.append(color)

yellow = Tkinter.Button(base, bd='0', highlightthickness='0',
                       width='7', height='5', activebackground='yellow',  
                       bg='yellow3', command = yellowClick)

yellow.place(x = 30, y = 50)

def blueClick():

    blue.configure(activebackground='medium blue')
    blue.after(500, lambda: blue.configure(activebackground='blue'))

    global clicks
    global color

    color = 2
    clicks.append(color)

blue = Tkinter.Button(base, bd='0', highlightthickness='0',
                     width='7', height='5', activebackground='blue',
                     bg='medium blue', command = blueClick)

blue.place(x = 125, y = 50)

def redClick():

    red.configure(activebackground='red3')
    red.after(500, lambda: red.configure(activebackground='red'))

    global clicks
    global color 

    color = 3
    clicks.append(color)

red = Tkinter.Button(base, bd='0', highlightthickness='0',
                    width='7', height='5', activebackground='red',
                    bg = 'red3', command = redClick)    

red.place(x = 30, y = 145)

def greenClick():

    green.configure(activebackground='dark green')
    green.after(500, lambda: green.configure(activebackground='green4'))

    global clicks
    global color

    color = 4
    clicks.append(color)

green = Tkinter.Button(base, bd='0', highlightthickness='0',
                      width='7', height='5', activebackground='green4',
                      bg='dark green', command = greenClick)

green.place(x = 125, y = 145)   

def scoreUp():

    global s

    s = s + 1

    scoreNum.configure(text = s)


sequence = []

def checkSequence():

    global clicks
    global sequence

    if clicks == sequence:

        scoreUp()   

def showSequence():

    global sequence
    global clicks
    global check 

    r = random.randint(1, 4)

    if r == 1:

        yellow.configure(bg='yellow')
        yellow.after(1000, lambda: yellow.configure(bg='yellow3'))

        sequence.append(r)

        base.after(5000, checkSequence)

    elif r == 2:

        blue.configure(bg='blue')
        blue.after(1000, lambda: blue.configure(bg='medium blue'))  

        sequence.append(r)

        base.after(5000, checkSequence)

    elif r == 3:

        red.configure(bg='red')
        red.after(1000, lambda: red.configure(bg='red3'))   

        sequence.append(r)

        base.after(5000, checkSequence)

    elif r == 4:

        green.configure(bg='green4')
        green.after(1000, lambda: green.configure(bg='dark green')) 

        sequence.append(r)      

        base.after(5000, checkSequence)


base.after(2000, showSequence)

fr.pack()

base.resizable(False, False)
base.mainloop()
</code></pre>

<p>The checkSequence function is activated by time because I could not find another way to do it.</p>

<p>Here is the code based on furas' solution in the comments</p>

<pre><code>def showSequence():

    global sequence    

    number_added = True
    r = random.randint(1, 4)

    if r == 1:
    elif r == 2:
    elif r == 3:
    elif r == 4:
    else:
        number_added = False

    return number_added # this will be True if a number was added, False if not
</code></pre>

<p>And to call the function:</p>

<pre><code>number_added = showSequence()
if number_added:
    # stop sequence here
</code></pre>

<p>You also said you don't know how to stop it, try this:</p>

<pre><code>import sys
sys.exit()
</code></pre>

<p>This will immediately stop the function you're currently in</p>
