I have a GN node tree with an output value as a float.
Blender tells me the path to it, which is great. And i got...if i execute it...an "x" ...umpf.
Hoped for a value. How do i get the value?

$\begingroup$ @MarkusvonBroady: but you are aware of the fact, that the question was asked 2022 and you add links from 2023? Makes less sense for me.... $\endgroup$– ChrisCommented Feb 29 at 12:01

$\begingroup$ why? It seems to you posting a link is some kind of a reprimand "you should have known about this because we already wrote about it before", whereas I treat them as signposts: we're here, look at the directions to ontological neighbors. $\endgroup$– Markus von BroadyCommented Feb 29 at 14:41

You need to refer to the object attributes, so if the attribute is a vector you can do:
obj = bpy.context.object.evaluated_get(bpy.context.evaluated_depsgraph_get()).data
obj.attributes[0].data[0].vector
You might need to adjust the indexes for your attributes.

2$\begingroup$ Hi! Is there a systematic way of chasing this kind of information down, or is it just something you have to know?, and is there a way of guaranteeing the index? e.g finding index for name? $\endgroup$– Robin Betts ♦Commented Jan 12, 2022 at 13:58
