Aide! Cette boucle while finit en quelque sorte jusqu'à l'infini ???????????? Noob ici. Cela fonctionne en dehors de Tkinter. J'ai littéralement copié et collé le code et il exécute juste pour toujours après avoir cliqué sur le bouton soumettre, le moteur continue à tourner et ne s'arrête pas. Il devrait casser quand Stepper = marqueur droit?

 while stepper!=marker: 
       print StepCounter, 
       print Seq[StepCounter], "stepper: ", (stepper), "Marker: ", (marker) 
       if (stepper<marker): 
        stepDir=-1 
       else: 
        stepDir=1 

       for pin in range(0, 4): 
        xpin = StepPins[pin] 
        if Seq[StepCounter][pin]!=0: 
         GPIO.output(xpin, True) 
        else: 
         GPIO.output(xpin, False) 
       marker+=stepDir 
       StepCounter += stepDir 

       # If we reach the end of the sequence 
       # start again 
       if (StepCounter>=StepCount): 
        StepCounter = 0 
       if (StepCounter<0): 
        StepCounter = StepCount+stepDir 

       # Wait before moving on 
       time.sleep(.006) 

       for pin in StepPins: 
        GPIO.output(pin, False) 
     SaveMarker(marker) 
     if content == marker: 
      message = "content" + str(content) 

     else: 
      print "success" 
      message ="marker" + str(marker) +"content" + str(content) 
     self.text.insert(0.0, message) 

root = Tk() 
root.title("Passwords") 
root.geometry("250x150") 
app=Application(root) 
root.mainloop() 
    # Start main loop 
#Old code 
#while True: 
# CallInput() 
# RunMotor(user) 

import atexit 
atexit.register(SaveMarker)

Il ressemble à stepper doit être convertie en une valeur numérique, probablement int:

stepper=self.userinput.get() 
... 
while stepper!=marker: 
    ... 
    if (stepper<marker): 
    ... 
    if content == marker: 
     message = "content" + str(content)
