title: python+raspberry pi gpio invalid syntax
body: <p>i am doing an internship and i need to come up with a Raspberry Pi that will have a clicker to add subtract 1 and reset to 0 for how many days accident free for the company and the site, here is the code i have but im getting an Invalid Syntax at the While True part, i have no experience in coding before this so any help would be great thanks!</p>
  
  <pre><code>GPIO.setmode(GPIO.BCM)
  GPIO.Setup (17, GPIO.IN, pull_up_down = GPIO.PUD_DOWN)
  GPIO.Setup (18, GPIO.IN, pull_up_down = GPIO.PUD_DOWN)
  GPIO.Setup (21, GPIO.IN, Pull_up_down = GPIO.PUD_DOWN)
  GPIO.Setup (22, GPIO.IN, pull_up_down = GPIO.PUD_DOWN)
  GPIO.setup (23, GPIO.IN, pull_up_down = GPIO.PUD_DOWN)
  GPIO.Setup (24, GPIO.IN, pull_up_down = GPIO.PUD_DOWN
      while True:
          Try:
          If(GPIO.input(17)== 1):
              writeTexts(+1,-370,55)
              writeTexts(today +difference1,-100,-200)
          If(GPIO.input(18)== 1):
              WriteTexts(-1,-370,55)
          If(GPIO.input(21)== 1):
              writeTexts(0,-370,55)
          If(GPIO.Input(22)==1):
              writeTexts(+1,280,55)
          If(GPIO.input(23)== 1):
              writeTexts(-1,280,55)
              writeTexts(today +difference1,550,-200)
          If(GPIO.input(24)==1):
              writeTexts(0,280,55)
              sleep(.01)
      except KeyboardInterrupt
          exit()
  GPIO.Cleanup ()
