Python 中的 SymPy |多面体. edges()
多面体. edges() : edges() 是一个返回多面体边缘的 sympy Python 库函数。
语法: 组合学.多面体.多面体.边()
返回: 多面体的边。
代码#1:边()示例–四面体
# Python code explaining
# SymPy.Polyhedron.edges()
# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.polyhedron import tetrahedron, octahedron
# Using from
# sympy.combinatorics.polyhedron.Polyhedron.edges()
# Creating Polyhedron
a = tetrahedron.copy()
print ("Polyhedron - edges form : ", a.edges)
a.rotate(0)
print ("\nPolyhedron - edges form : ", a.edges)
输出:
多面体–边的形式:{(0,1),(0,2),(0,3),(1,2),(1,3),(2,3)}
多面体–边的形式:{(0,1),(0,2),(0,3),(1,2),(1,3),(2,3)}
代码#2:边()示例–八面体
# Python code explaining
# SymPy.Polyhedron.edges()
# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.polyhedron import tetrahedron, octahedron
# Using from
# sympy.combinatorics.polyhedron.Polyhedron.edges()
# Creating Polyhedron
a = octahedron.copy()
print ("Polyhedron - edges form : ", a.edges)
a.rotate(0)
print ("\nPolyhedron - edges form : ", a.edges)
输出:
多面体–边的形式:{(0,1),(0,2),(0,3),…,(3,4),(3,5),(4,5)}
多面体–边的形式:{(0,1),(0,2),(0,3),…,(3,4),(3,5),(4,5)}
