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