Loading a gh file, executing it and harvesting its data

This came up in private tech-support, may be useful for others as well.
The attached Runner.gh file loads another gh file (example provided), sets a value to a parameter named “INPUT”, runs it, harvests the data in the parameter called “OUTPUT” and then outputs that as its own data.

I tried to translate the script Runner in Python language but it doesn’t work. Can someone help me ? I’m close…
Runner.gh (5.5 KB)

I did’nt succed in translating this script into python. So I decided to implement it into a grasshopper file that I turned into a Rhino Command named GrasshopperPlayerOnce
Instead of
-GrasshopperPlayer "xx.gh"
I use
-GrasshopperPlayerOnce "xx.gh"
It works well. The file is joined

Since a newer version, my python script started working.

Here is a GHPython component calling another Grasshopper file.

It solve one of the limits of Hops Plugin, you can execute another Grasshopper containing some external plugin.

Thanks, your script works pretty well for me. It´s sad that the grasshopper player is not really suited for more complex tasks (e.g. it keeps running in the background). Your script is exactly what I need. Thank you Gaspard!
