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

Permutation.mul_inv()：mul_inv()是一个sympy Python库函数，该函数返回mul反向other *〜self，self和other具有_array_form。

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

返回：mul反向其他*〜self，self和other具有_array_form。

代码1：mul_inv()示例

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

输出：

Permutation a – mul_inv form : (3)
Permutation b – mul_inv form : (5)
