# SymPy | Polyhedron.corners() in Python

• Last Updated : 27 Aug, 2019

Polyhedron.corners() : corners()
is a sympy Python library function that returns the corners of the Polyhedron.

Syntax :
sympy.combinatorics.Polyhedrons.Polyhedron.corners()

Return :
corners of the Polyhedron

Code #1 : corners() Example – tetrahedron

 `# Python code explaining``# SymPy.Polyhedron.corners()`` ` `# importing SymPy libraries``from` `sympy.combinatorics ``import` `Permutation, Cycle``from` `sympy.combinatorics.polyhedron ``import` `tetrahedron, octahedron`` ` `# Using from ``# sympy.combinatorics.polyhedron.Polyhedron.corners()`` ` `# Creating Polyhedron``a ``=` `tetrahedron.copy()`` ` `print` `(``"Polyhedron - corners form : "``, a.corners)`` ` `a.rotate(``0``)``print` `(``"\nPolyhedron - corners form : "``, a.corners)`

Output :

Polyhedron – corners form : (0, 1, 2, 3)

Polyhedron – corners form : (0, 2, 3, 1)

Code #2 : corners() Example – octahedron

 `# Python code explaining``# SymPy.Polyhedron.corners()`` ` `# importing SymPy libraries``from` `sympy.combinatorics ``import` `Permutation, Cycle``from` `sympy.combinatorics.polyhedron ``import` `tetrahedron, octahedron`` ` `# Using from ``# sympy.combinatorics.polyhedron.Polyhedron.corners()`` ` `# Creating Polyhedron``a ``=` `octahedron.copy()`` ` `print` `(``"Polyhedron - corners form : "``, a.corners)`` ` `a.rotate(``0``)``print` `(``"\nPolyhedron - corners form : "``, a.corners)`

Output :

Polyhedron – corners form : (0, 1, 2, 3, 4, 5)

Polyhedron – corners form : (0, 2, 3, 4, 1, 5)
