Hi Eghbalpourf

try this：

import rhinoscriptsyntax as rs
import Rhino.Geometry as rg

faces = mesh.Faces
a = [face.IsQuad for face in faces]

If you want to know if a mesh is consisting of only quads maybe easier to use TriangleCount or QuadCount:

a = mesh.Faces.TriangleCount == 0 # mesh has no (valid) triangles, only (valid) quads
