运行具有连续输出的python程序。我想用Flask把输出发送到一个网页。我怎么能做到呢？

Question

import Leap, sys, thread, time
from Leap import CircleGesture, KeyTapGesture, ScreenTapGesture, SwipeGesture
from flask import Flask
class LeapMotionListener(Leap.Listener):
finger_names = ['Thumb', 'Index', 'Middle', 'Ring', 'Pinky']
bone_names = ['Metacarpal','Proximal','Intermediate', 'Distal']
state_names = ['STATE_INVALID', 'STATE_START','STATE_UPDATE','STATE_END']

def on_init(self, controller):
    print "Initialized"

def on_connect(self, controller):
    print "Motion Sensor Connected!"

    controller.enable_gesture(Leap.Gesture.TYPE_CIRCLE);
    controller.enable_gesture(Leap.Gesture.TYPE_KEY_TAP);
    controller.enable_gesture(Leap.Gesture.TYPE_SCREEN_TAP);
    controller.enable_gesture(Leap.Gesture.TYPE_SWIPE);

def on_disconnect(self, controller):
    print "Motion Sensor Disconnected"

def on_exit(self, controller):
    print "Existed"

 def on_frame(self, controller):
    frame = controller.frame()

    #print " Number of Hands: " + str(len(frame.hands))
    hand = str(len(frame.hands))
    print hand
    return hand
def main():
   listener = LeapMotionListener()
   controller = Leap.Controller()
   controller.add_listener(listener)

print "Press enter to quit"
try:
    sys.stdin.readline()

except keyboardInterrupt:
    pass
finally:
    controller.remove_listener(listener)

  if __name__ == "__main__":
  main()

输出为： 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 111111 0 0 0 0 0 0 0 0 0 0 0 一直持续到我终止程序。在

我希望这个输出被发送到网页使用烧瓶。我该怎么做？在

注：以上是一个leapmotion手检测程序。上面的程序只运行在python32位和leapmotionsdk上

Answer 1

编写程序，使连续输出是生成器的结果，然后给生成器一个烧瓶响应。在
