Python Sympy Permutation.order()用法及代码示例

Permutation.order()：order()是一个sympy Python库函数，用于计算排列顺序。当将排列提升到其顺序的幂时，则在这种情况下，顺序等于标识排列。

用法： sympy.combinatorics.permutations.Permutation.order()

返回：排列顺序

代码1：order()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：

Permutation a – order form : 2
Permutation b – order form : 6

代码2：order()示例– 2D排列

# 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, 4, 0],  
                 [3, 1, 2], 
                 [1, 5, 6]]) 
  
  
print ("Permutation a - order form : ", a.order())

输出：

Permutation a – order form : 7
