Sorry for such easy task, but for me it is a huge problem. I am new in Revit, and don't familiar with more methods in Revit, all information that I can find is for C# and VB.
How to create new parameter for an element and put there some text in Python?
Fo example I need to filter all pipes in my project, set a new parameter in builtin parameters group ("Identity Data" or "Data") with name "My First Parameter" and set the value for each pipe "My Pipe".
