thanks @LoganByers, the question is how to get the raster attribute table usingpython 3.6 and gdal 2.1.3. Sorry, I should have been clearer

thanks @xunilk, I would really appreciate if you have any example or could point me to one.

thanks @xunilk, I do not have a circle shapefile though. I want to create it based on command line value. Similar to how I do not have a rectangle shapefile but can use gdalwarp to specify bounding box. Is there a command to create the circle shapefile?
