Python Sympy Polyhedron.edges()用法及代碼示例

Polyhedron.edges()：edges()是一個sympy Python庫函數，它返回多麵體的邊。

用法：

sympy.combinatorics.Polyhedrons.Polyhedron.edges()

返回：
多麵體的邊。

代碼1：edges()示例–四麵體

# 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)

輸出：

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)}

代碼2：edges()示例–八麵體

# 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)

輸出：

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)}
