[fix] : Windows open cam handle

[CourageTrain]

All I did is the following -

try:
   # while running: ->pygame 
catch Exception as e:
   # print("Exception : {details}")
finally:
   pygame.quit()
   cap.close()   # necessary to avoid the open cam handle issue
   cv2.destroyAllWindows() # destroys openCV windows
   sys.exit() # closes current run on cmdline

Hey,

I think it is not really beneficial to cover entire example code with try catches. It makes examples look more complicated and may hide other problem.

Issue with the open cam handle, it should be dealt inside library not outside of it.

Thanks.
