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

Permutation.parity()：parity()是一個sympy Python庫函數，它返回置換的奇偶校驗。這意味著排列中反轉數量的奇偶性。

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

返回：詞典順序的下一個排列

代碼1：parity()示例

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

輸出：

Permutation a – parity form : 0
Permutation b – parity form : 1
