Python Nodes Basics



I noticed it might be useful to gather some Python related posts in one thread to make it easy to get started with some basic understanding (and also for a consultation ease purpose). This is still a work in progress and there might be some slight inconsistencies. Feel free to add your own links or Python related comments, or to PM me on anything that should be revised. This first post relates naturally to tips for LEARNING PYTHON:

List Appearance Assets for Material
Looking for a Simple Python script to create Table (solved without python)
Find nodes and packages in use in a graph

This second post relates to IMPORTS:

I wrote a 30 page handout for my AU class on Python for Dynamo, thought I would leave this here


This is a very good document that let you get started with a clear view on the possibilities opened by this language, along with a few tips that will make it all fun from the start. I add a link into the introductory post so it can be found easily. Thanks a lot :grinning:


Hooray for this post


It seems consistent to add this other nice tutorial here:
