Pythonstuff from Codeacademy and import Revit API

Hello Dynos,

I do some exercises between Revit | Dynamo | Python

1.) How can i output negativ values ? -10, -1.41, …

2.) How can I make a list, which contains “comments”? right now a have a list of 42 (items ?, Comments?,…)

I am glad about any advice, and also some practicle stuff that i can convert to benefits of Workflows

Thank you

Sorry i did not shoot the last script: what is in this “library” clr included?
And why get a 42 “items” listed - Where do the come from? designScript? Revit API?
I have no clue

Thank you,

How can I access the Revit API? also in this way?
