Python Sympy Permutation.transpositions()用法及代碼示例

Permutation.transpositions()：transpositions()是一個sympy Python庫函數，它返回分解為換位列表的置換。始終可以將置換表示為換位的乘積。

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

返回：排列分解為換位列表

代碼1：transpositions()示例

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

輸出：

Permutation a – transpositions form : [(0, 2), (1, 3)]
Permutation b – transpositions form : [(0, 5), (0, 2), (0, 4), (0, 3), (0, 1)]

代碼2：transpositions()示例

# importing SymPy libraries 
from sympy.combinatorics.partitions import Partition 
from sympy.combinatorics.permutations import Permutation 
  
# Using from

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

輸出：

Permutation a – transpositions form : [(0, 4), (0, 2), (0, 1), (0, 6), (0, 5), (0, 3)]
