How Has This Been Tested?

I tested the fix using python 3 and my Jetson Nano

Before :

SyntaxError: invalid syntax
hicham@ted:~/Dev/jetsonDevices/CSI-Camera$ python3 simple_camera.py 
  File "simple_camera.py", line 27
    print gstreamer_pipeline(flip_method=0)
                           ^
SyntaxError: invalid syntax
hicham@ted:~/Dev/jetsonDevices/CSI-Camera$ python3 simple_camera.py 
  File "simple_camera.py", line 43
    print 'Unable to open camera'

After :

Thank you very much for this. I had other changes at the same time, so I did not do a straight pull.
