How to fix infinite loop in python

manpreet Best Answer 2 years ago

I just started with python and RPi. But i stuck :D I have 4 microswitches, and few posibilities (BC1, BC2, BC3... etc). For example, if we choose posibility BC1, then microswitch 1 (btn1) and 2 (btn2) must be active, if that case is true, then ledG1 and vazduh are active. Also I need to have a posibiliti to insert another posibiliti (BC1, BC2, BC3), and untill we insert another posibility first must be active (if requested switches are active).

With this de">code it's working, but ask me only once to insert possibility.

BC1 = '1'
BC2 = '2'
BC3 = '3'
BC4 = '4'
BC5 = '5'

def compare ():
    while True:
        Barde">code = input("Insert barde">code: ")
        while Barde">code == BC1:
            if GPIO.input(btn1)==0 and GPIO.input(btn2)==0:
                GPIO.output(vazduh, GPIO.HIGH)
                GPIO.output(ledG1, GPIO.HIGH)
                continue
            else:
                GPIO.output(vazduh, GPIO.LOW)
                GPIO.output(ledG1, GPIO.LOW)
                continue                
        while Barde">code == BC2:
            if GPIO.input(btn2)==0 and GPIO.input(btn4)==0:
                GPIO.output(vazduh, GPIO.HIGH)
                GPIO.output(ledG3, GPIO.HIGH)
                continue
            else:
                GPIO.output(vazduh, GPIO.LOW)
                GPIO.output(ledG3, GPIO.LOW)
                continue

I think you probably wanted to use if instead of while in your first while's scope.

while True:
   Barcode = input("Insert barcode: ")
   if Barcode == BC1:
      #Do something #1
   if Barcode == BC2:
      #Do something #2
