SymPy | Python中的 Polyhedron.size()

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

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

Return : count of number of corners of the polyhedron

代码 #1：size() 示例——四面体

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

输出 ：

Polyhedron – size form : 4

Polyhedron – size form : 4

代码 #2 : size() 示例 – 八面体

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

输出 ：

Polyhedron – size form : 6

Polyhedron – size form : 6
