ghpythonlib.components problem

Hi everyone

I am new to python, and even newer to python in grasshopper. When I try to use ghpythonlib.components Length function I get null/none instead of number. 

This is my code (also attached):

import ghpythonlib.components as ghcomp

a = ghcomp.Length(x)

What am I missing here?

Hi Maciej,

That is quite usual question for all beginners.

You need to set your "Type hint" to "Curve" instead of "ghdoc Doc" which is by default.
Grasshopper requires objects to work on, not guids.
