Python中的SymPy Polyhedron.array_form()

Polyhedron.array_form() : array_form()是一个Sympy Python库函数，用于返回多面体的角的索引。

语法 : sympy.combinatorics.Polyhedrons.Polyhedron.array_form()

返回 :
多面体的角的指数

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]
