Dynamo, Python library and finding what I can import from it

1

Hi all,

I would like to understand how “importing” works, vague I know but I hope to get better at asking my quesions as I understand more.

I ran across a post here, that allowed a pythin script to act as a File.FromPath node

from System.IO import FileInfo
file = FileInfo(IN[0])

My first question is ‘from System.IO import FileInfo’ Where do I start to look to find what I an import from System.IO, how do I find what I can import from this and different libraries?

I am new to python and programming in general, I have much experiance with AutoLisp, so I sort of understand some concepts but lost most of the time.

Thanks any help

Hi @cadman6735

Once you import System you just have to type OUT = dir(System.IO) to get all libraries. Cheers!

If you want more info on libraries of Python, Dynamo uses 2.7 version of python so you can search using that. The main 2.7 website is here: https://docs.python.org/2.7/
And here are the libraries: https://docs.python.org/2.7/library/
