How to access CreateSmoothingBlocks from python for fes?

list and set shouldn't make a difference, in Python we use set to prevent double entries.

You could create a separate Python function that takes in a table and returns a smoother.

Oh, yes. I can create a python function that takes in a table, and a basematrix to directly create the smoother. This approach further speed up the process by about a factor of 2. Thanks again!
For the timing of constructing a vertex patch block in 3D, python looping is about 200 times slower than the C++ looping (the AFW block in edge space) in my machine, which I found quite interesting.

Yes, this is to be expected. The pythonic way of creating the smoother is certainly more for studying purposes than for production code.
