Hi,
I am trying to make a python OOT with 2 i/p & 1 o/p port.
The 1st i/p port should act like a trigger. For example whenever a ‘1’ is found
in 1st input port, first 2 items in the list of 2nd input port will pass
through, else dropped.
I have written the code as follows but its giving me an error: Can you help me
in finding out where is the mistake?
