Python 中的 SymPy | arrange.random()
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

# importing SymPy libraries
from sympy.combinatorics.partitions import Partition
from sympy.combinatorics.permutations import Permutation
# Using from

# 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)
