Issues with programming leap motion in python on linux

[Geeve]

Hi Everyone,

I'm using the Leap motion V2.3.1 Python SDK on linux.
I am running the following code below

import os, sys, inspect, thread, time
src_dir = os.path.dirname(inspect.getfile(inspect.currentframe()))

Windows and Linux

arch_dir = '../lib/x64' if sys.maxsize > 2**32 else '../lib/x86'

Mac

arch_dir = os.path.abspath(os.path.join(src_dir, '../lib'))

sys.path.insert(0, os.path.abspath(os.path.join(src_dir, arch_dir)))

import Leap

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

print "Frame id: %d, timestamp: %d, hands: %d, fingers: %d" % (
      frame.id, frame.timestamp, len(frame.hands), len(frame.fingers))

class SampleListener(Leap.Listener):

def on_connect(self, controller):
    print "Connected"


def on_frame(self, controller):
    print "Frame available"

def main():

# Create a sample listener and controller
listener = SampleListener()
controller = Leap.Controller()

# Have the sample listener receive events from the controller
controller.add_listener(listener)

# Keep this process running until Enter is pressed
print "Press Enter to quit..."
try:
    sys.stdin.readline()
except KeyboardInterrupt:
    pass
finally:
    # Remove the sample listener when done
    controller.remove_listener(listener)

if name == "main":
main()

But I'm not able to get the finger id , number of fingers etc. outputs on the python shell.
I've attached a screenshot, I only get connected, and the program says to press enter.

Hope you could help me resolve this issues.

Thank you!
