SymPy | Python中的 Polyhedron.corners()

Polyhedron.corners() ：corners()是一个 sympy Python库函数，它返回多面体的角。

Syntax :
sympy.combinatorics.Polyhedrons.Polyhedron.corners()

Return :
corners of the Polyhedron

代码#1：corners() 示例——四面体

# Python code explaining
# SymPy.Polyhedron.corners()
  
# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.polyhedron import tetrahedron, octahedron
  
# Using from 
# sympy.combinatorics.polyhedron.Polyhedron.corners()
  
# Creating Polyhedron
a = tetrahedron.copy()
  
print ("Polyhedron - corners form : ", a.corners)
  
a.rotate(0)
print ("\nPolyhedron - corners form : ", a.corners)

输出 ：

Polyhedron – corners form : (0, 1, 2, 3)

Polyhedron – corners form : (0, 2, 3, 1)

代码#2：corners() 示例——八面体

# Python code explaining
# SymPy.Polyhedron.corners()
  
# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.polyhedron import tetrahedron, octahedron
  
# Using from 
# sympy.combinatorics.polyhedron.Polyhedron.corners()
  
# Creating Polyhedron
a = octahedron.copy()
  
print ("Polyhedron - corners form : ", a.corners)
  
a.rotate(0)
print ("\nPolyhedron - corners form : ", a.corners)

输出 ：

Polyhedron – corners form : (0, 1, 2, 3, 4, 5)

Polyhedron – corners form : (0, 2, 3, 4, 1, 5)
