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

Permutation.random()：random()是一个sympy Python库函数，它返回长度为'n'的随机排列。

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

返回：长度的随机排列

代码1：random()示例

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

输出：

Permutation a – random form : (1)
Permutation b – random form : (4)

代码2：random()示例– 2D排列

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

输出：

Permutation a – random form : (0 1 2 3)
