SymPy | Python中的 Permutation.is_Singleton()

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。

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 :
