Polyhedron.array_form() : array_form() is a sympy Python library function that returns the indices of the corners of polyhedron.
Syntax :
sympy.combinatorics.Polyhedrons.Polyhedron.array_form()Return :
indices of the corners of polyhedron
Code #1 : array_form() Example – tetrahedron
# Python code explaining # SymPy.Polyhedron.array_form() # importing SymPy libraries from sympy.combinatorics import Permutation, Cycle from sympy.combinatorics.polyhedron import tetrahedron, octahedron # Using from # sympy.combinatorics.polyhedron.Polyhedron.array_form() # Creating Polyhedron a = tetrahedron.copy() print ("Polyhedron - array_form form : ", a.array_form) a.rotate(0) print ("\nPolyhedron - array_form form : ", a.array_form) |
Output :
Polyhedron – array_form form : [0, 1, 2, 3]
Polyhedron – array_form form : [0, 2, 3, 1]
Code #2 : array_form() Example – octahedron
# Python code explaining # SymPy.Polyhedron.array_form() # importing SymPy libraries from sympy.combinatorics import Permutation, Cycle from sympy.combinatorics.polyhedron import tetrahedron, octahedron # Using from # sympy.combinatorics.polyhedron.Polyhedron.array_form() # Creating Polyhedron a = octahedron.copy() print ("Polyhedron - array_form form : ", a.array_form) a.rotate(0) print ("\nPolyhedron - array_form form : ", a.array_form) |
Output :
Polyhedron – array_form form : [0, 1, 2, 3, 4, 5]
Polyhedron – array_form form : [0, 2, 3, 4, 1, 5]
