How to get a single object or some in paraview python?

[jone]

I rendered some data on the server side in python, like this:

> reader = simple.OpenDataFile('xxx.obj')
> simple.Show(reader)
> simple.Render()

And I want to customize some protocols such as pick or clip one of the objects I rendered. I tried some methods, but it didn’t have the right effect. Do the experts have any good advice? Thank you in advance!
