# SymPy | Polyhedron.rotate() in Python

Polyhedron.rotate() : rotate() is a sympy Python library function that rotation about an axis of the polyhedra.

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

Return : rotation about an axis of the polyhedra

Code #1 : rotate() Example – tetrahedron

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

Output :

Polyhedron – rotate form : [0, 1, 2, 3]

Polyhedron – rotate form : [0, 2, 3, 1]

Code #2 : rotate() Example – octahedron

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

Output :

Polyhedron – rotate form : [0, 1, 2, 3, 4, 5]

Polyhedron – rotate form : [0, 2, 3, 4, 1, 5]
