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

Permutation.is_Singleton()：is_Singleton()是一个sympy Python库函数，用于检查排列是否仅包含一个元素。

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

返回：true –如果排列仅包含一个元素；否则为假

代码1：is_Singleton()示例

# Python code explaining 
# SymPy.Permutation.is_Singleton() 
  
# importing SymPy libraries 
from sympy.combinatorics.partitions import Partition 
from sympy.combinatorics.permutations import Permutation 
  
# Using from sympy.combinatorics.permutations.Permutation.is_Singleton() method  
  
# creating Permutation 
a = Permutation([[2, 0], [3, 1]]) 
  
b = Permutation([0]) 
  
  
print ("Permutation a - is_Singleton form : ", a.is_Singleton) 
print ("Permutation b - is_Singleton form : ", b.is_Singleton)

输出：

Permutation a – is_Singleton form : False
Permutation b – is_Singleton form : True

代码2：is_Singleton()示例– 2D排列

# Python code explaining 
# SymPy.Permutation.is_Singleton() 
  
# importing SymPy libraries 
from sympy.combinatorics.partitions import Partition 
from sympy.combinatorics.permutations import Permutation 
  
# Using from sympy.combinatorics.permutations.Permutation.is_Singleton() method  
  
# creating Permutation 
a = Permutation([[2, 4, 0],  
                 [3, 1, 2], 
                 [1, 5, 6]]) 
  
  
print ("Permutation a - is_Singleton form : ", a.is_Singleton)

输出：

Permutation a – is_Singleton form : False
