Python SymPy Permutation.commutes_with()用法及代码示例

Permutation.commutes_with():commutes_with()是一个sympy Python库函数,用于检查两个置换是否在交换。假设“ a”和“ b”是“ C”的一部分,则a和b的换向器是a和b上下班的“ C”标识,即ab == ba。

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

返回:
检查两个排列是否在换向


代码1:commutes_with()示例

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

输出:

Permutation a – commutes_with form : False
Permutation b – commutes_with form : False

代码2:commutes_with()示例–自换向器

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

输出:

Permutation a – commutes_with form : True
