SymPy Python中的Polyhedron.edges()

Polyhedron.edges() : edges()是一个Sympy Python库函数，用于返回多面体的边缘。

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

返回 :
多面体的边缘。

代码 #1 : edges() 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 :

Polyhedron – edges form : {(0, 1), (0, 2), (0, 3), (1, 2), (1, 3), (2, 3)}

Polyhedron – edges form : {(0, 1), (0, 2), (0, 3), (1, 2), (1, 3), (2, 3)}

代码 #2 : edges() 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 :

Polyhedron – edges form : {(0, 1), (0, 2), (0, 3), …, (3, 4), (3, 5), (4, 5)}

Polyhedron – edges form : {(0, 1), (0, 2), (0, 3), …, (3, 4), (3, 5), (4, 5)}
