Windows PowerShell不退出腳本與Ctrl-C

所以我在Windows上運行Python 3.4腳本，當我運行一個特定的腳本時，我有一個無限循環（而真正的:)我正在使用，但是當我嘗試用Ctrl-C退出腳本，它不會退出腳本。它打印鍵盤中斷，彷彿它已經退出，但後來只留下閃爍的光標，不會讓我的類型，所以我與紅色的X可以退出Windows PowerShell不退出腳本與Ctrl-C

#from pyfirmata import Arduino, util, PWM 

board = pyfirmata.Arduino('COM4', baudrate = 9600, timeout = 5) 
time.sleep(2)  #sleep in units of sec 

it = pyfirmata.util.Iterator(board) 
it.start() 


digital1 = board.get_pin('d:5:p') 
digital2 = board.get_pin('d:6:p')

      left = 1 
      leftMid = (forceGraspL - motorMaxForceL)/ motorMaxForceL 
      right = forceGraspR/motorMaxForceR

      right = 1 
      rightMid = (forceGraspR - motorMaxForceR)/ motorMaxForceR 
     elif (forceGraspL < maxForceL and forceGraspR < maxForceR): 
      left = 1 
      leftMid = (forceGraspL - motorMaxForceL)/ motorMaxForceL 
      right = 1 
      rightMid = (forceGraspR - motorMaxForceR)/ motorMaxForceR 
     else: 
      left = 1 
      leftMid = 1 
      rightMid = 1 
      right = 1 

     if (distPerc < 100 and distPerc > 0): 
      for pin in range(1, length(digital)): 
       digital[pin].write(MOTORS(pin)) 
      time.sleep(.5) 
      for pin in range(1, length(digital)): 
       digital[pin].write(0) 
      time.sleep(.5) 

     else: 
      for pin in range(1, length(digital)): 
       digital[pin].write(MOTORS(pin))

任何建議什麼我的腳本可能會造成這個問題，非常感謝。我可以告訴問題出在這個腳本中，因爲我嘗試了無限循環的其他腳本，並且Ctrl-C適用於這些腳本。

你如何在PowerShell中運行Python腳本？ – briantist

我將目錄更改爲腳本所在的位置以及我可以訪問python的位置，然後使用命令> python filename.py運行腳本。我對python相當陌生，並且僅遵循如何學習Python Hard Work網站所述的協議。運行Python腳本的標準方式是什麼？ – rtmurad

我已經從問題中刪除了powershell標記。如果這個問題只發生在你從powershell提示符（我認爲不太可能）啓動python的時候，那麼你可以添加它，但是請編輯你的問題來澄清是否是這種情況。 – briantist

我發現貼在源網頁的問題的答案：

https://github.com/tino/pyFirmata

這是位於原代碼，從該代碼序列（我離開了上面的代碼中的錯誤原來，道歉！）：

it = pyfirmata.util.Iterator(board) 
it.start()

但是，你不能擺脫這個代碼，否則串行緩衝區將過載。
