How to select all shapes in a layer and round corners in Python

I have many rectangles in a layer and I put them in a region. Now I would like to select each of them and the round corners. It is possible to do this using Python?

Edit: I tried to use the code below. But nothing happened after I ran my code. All the polygons remain the same. My polygons are simply 30um by 30um squares.

      for shapeObj in cell.each_shape(layer_index): #shapeObj is polygon
          shapeObj.polygon.round_corners(1000,1000,16)

Thanks in advance!

    The problem is that "Shape.polygon" returns a copy - you only modify the copy, not the original polygon which is an opaque binary object inside the database.

    To write the polygon back, use

    shapeObj.polygon = shapeObj.polygon.round_corners(1000,1000,16)
