代码1：array_form()示例–四面体

# 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)

输出：

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

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

代码2：array_form()示例–八面体

# 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)

输出：

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

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