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

Permutation.rmul()：rmul()是一个sympy Python库函数，它返回置换的乘积。

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

返回：排列的乘积。

代码1：rmul()示例

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

输出：

Permutation a – rmul form : (0 1 3 4 2 5)
Permutation b – rmul form : (0 2)(1 3)

代码2：rmul()示例– 2D排列

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

输出：

Permutation a – rmul form : (0 3 5 6 1 2 4)
