Python 中的 SymPy |多面体. array_form()

原文:https://www.geesforgeks.org/sympy-多面体-array_form-in-python/

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

语法: sympy.combinarics .多面体.多面体. array_form()

返回: 多面体角的指数

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:

多面体–数组形式:[0,1,2,3]

多面体–数组形式:[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:

多面体–数组形式:[0,1,2,3,4,5]

多面体–数组形式:[0,2,3,4,1,5]
