Updating polygon geometry: deleting inner rings with python

I've found the solution with arcgisscripting, if anyone gona need to automate it.

It's really simple,.. just required some time to catch those holes :)

rows=gp.UpdateCursor(shp) #everything is done with one Cursor, but couple of arrays
row=rows.Next()
try:
    while row:
        if row.shape.area < 200:  #it's just deleting small polygons
            rows.DeleteRow(row)
        else:                     #part of cleaning from inner rings (donuts)
            geom=row.shape
            array=geom.GetPart(0)
            pnt=array.Next()
            newarray = gp.CreateObject("Array") #writing geometry to newArray       
            while pnt:
                newarray.add(pnt)
                pnt=array.Next()
                newpnt=newarray.Next()
                if not pnt:                     #this is the HOLE! 
                    break                       #when detect - break the loop!
            row.shape=newarray
            rows.UpdateRow(row)
        row=rows.Next()

    del row
    del rows
except:
    gp.GetMessages()

The part about deleting the features. Seems it's often not allowed. Found, there is a possibilty to test it: http://www.gdal.org/ogr/classOGRLayer.html#aeedbda1a62f9b89b8e5f24332cf22286

layer.TestCapability("DeleteField")

and so I get False..

And accessing just the first ring goes well, I've checked with area calculations.

The solution then is just to CREATE a new file with features I need from old file.. Correct me if I am misstaken.
