Derived from mel command maya.cmds.setDefaultShadingGroup

Example:

import pymel.core as pm

# Create a new blue shader
blinn = pm.shadingNode( 'blinn', asShader=True )
pm.setAttr( blinn+".color", 0.15, 0.35, 1.0,  type='double3' )
blinnSG = pm.sets( renderable=True, noSurfaceShader=True, empty=True, name='blinnSG' );
pm.connectAttr( blinn+".outColor", blinnSG+".surfaceShader", force=True)

# Make it the default
pm.setDefaultShadingGroup( blinnSG )
