Im curious of how to automate creation of shader nodes and and end up with an image texture connected to the color-input of a Principled BSDF.

This would have been easy if copy-pasting from info-console was possible as it is with creating and smoothing a mesh for instance, but for some reason doesnt work here. (I have made sure to enable nodes)

Obviously I'm fairly new to scripting in Blender.

Any response is greatly appreciated :)

Thank you! Probably but I'm getting an error at the line: nodes = mat.node_tree.nodes – vilhelm Jul 25 '21 at 18:03
From console: AttributeError: 'NoneType' object has no attribute 'node_tree' – vilhelm Jul 25 '21 at 18:03
No problem. Create a material in the first place and enable 'use nodes', then run the script (... and set the path to your texture). – brockmann Jul 25 '21 at 18:06
Fantastic, thanks. That got us past that, but seems to be one last problem with the path
From console: RuntimeError: Error: Cannot read 'C: estImg\ironman_whammmm.jpg': Invalid argument

Heres the line: node_tex.image = bpy.data.images.load("C:\testImg\ironman_whammmm.jpg") – vilhelm Jul 25 '21 at 18:37
Try: C:\\testImg\\ironman_whammmm.jpg – brockmann Jul 25 '21 at 18:49
