need help with ultrasonic sensor code

[gontajones]

Maybe something like this...using a control flag (run_script) to avoid multiple calls of test.sh.

def main():

    try:
        run_script = True
        while True:
            Ergebnis = MesseDistanz()
            print("Gemessene Entfernung: %.1f cm (Signallaufzeit: %.4fms)" % (Ergebnis[0], Ergebnis[1]))
            if Ergebnis[0] < 10 and run_script:
                os.system('/home/pi/test.sh')
                run_script = False
            if Ergebnis[0] >= 10:
                run_script = True
            time.sleep(1)

    except KeyboardInterrupt:
        print("Messung abgebrochen")
        GPIO.cleanup()
