多面体. cyclic_form() : cyclic_form() 是一个 sympy Python 库函数，返回循环记数法中的角的索引。
语法: 符号组合学.多面体.多面体.循环形式()
返回: 循环符号中的角索引
代码#1:循环形式()示例–四面体
# Python code explaining
# SymPy.Polyhedron.cyclic_form()
# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.polyhedron import tetrahedron, octahedron
# Using from
# sympy.combinatorics.polyhedron.Polyhedron.cyclic_form()
# Creating Polyhedron
a = tetrahedron.copy()
print ("Polyhedron - cyclic_form form : ", a.cyclic_form)
a.rotate(0)
print ("\nPolyhedron - cyclic_form form : ", a.cyclic_form)
输出:
多面体–循环形式形式:[]
多面体–循环形式形式:[[1，2，3]]
代码#2:循环形式()示例–八面体
# Python code explaining
# SymPy.Polyhedron.cyclic_form()
# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.polyhedron import tetrahedron, octahedron
# Using from
# sympy.combinatorics.polyhedron.Polyhedron.cyclic_form()
# Creating Polyhedron
a = octahedron.copy()
print ("Polyhedron - cyclic_form form : ", a.cyclic_form)
a.rotate(0)
print ("\nPolyhedron - cyclic_form form : ", a.cyclic_form)
输出:
多面体–循环形式形式:[]
多面体–循环形式形式:[[1，2，3，4]]
