Python 中的 SymPy | arrange.order()
排列顺序() :顺序()是一个计算排列顺序的 sympy Python 库函数。当置换被提升到它的阶的幂时,那么,在这种情况下,阶等于单位置换。
语法:组合学.排列.排列.顺序()
返回:排列的顺序
代码#1:订单()示例
# Python code explaining
# SymPy.Permutation.order()
# importing SymPy libraries
from sympy.combinatorics.partitions import Partition
from sympy.combinatorics.permutations import Permutation
# Using from sympy.combinatorics.permutations.Permutation.order() method
# creating Permutation
a = Permutation([[2, 0], [3, 1]])
b = Permutation([1, 3, 5, 4, 2, 0])
print ("Permutation a - order form : ", a.order())
print ("Permutation b - order form : ", b.order())
输出:
排列 a–顺序形式:2 排列 b–顺序形式:6
