Is there a way to ask Sage to count the number of lattice points in a rational polytope, say a polytope with vertices (0,0,0,0), (0,0,0,7), (0,0,7/2,7/2), (0,7/3,7/3,7/3),(7/4,7/4,7/4,7/4)?

There is

sage: P = Polyhedron([(0,0,0,0), (0,0,0,7), (0,0,7/2,7/2), (0,7/3,7/3,7/3),(7/4,7/4,7/4,7/4)])
sage: P.integral_points_count()
38
