replacement . random():random()是一个 sympy Python 库函数，返回长度为‘n’的随机置换。

语法:sympy . combinations .排列.置换. random()

返回:长度的随机排列

代码#1:随机()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:

排列 a–随机形式:(1) 排列 b–随机形式:(4)

代码#2:随机()示例–2D 置换

# 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:

排列 a–随机形式:(0 1 2 3)
