How can i use this python script to define a block in grasshoppper?

You need to change the scriptcontext when targeting the Rhino document from a GHPython script. See this thread:

Create linear / rectangular lights in grasshopper!

Hi guys. If you want to fiddle with the Rhino document from GHPython, you must explicitly set the script context to target the Rhino document. Here’s one approach: import Rhino as rc import scriptcontext as sc import rhinoscriptsyntax as rs # Set context to Rhino document and disable redraw sc.doc = rc.RhinoDoc.ActiveDoc rs.EnableRedraw(False) # Fiddle with the Rhino document # Set context back to Grasshopper rs.EnableRedraw(True) sc.doc = ghdoc

Edit: Here’s a quick implementation:
