python - 在 Python 中随机化所有可能的组合

Question

这是我的代码：

基本上，它的作用是根据 a、c、d、e 的所有组合从不同的列表中提取，并使 a 和 b 对应。这段代码工作正常，但不是很漂亮。我想知道是否有人对我用更少的代码行做同样的事情有任何建议。最重要的是，我只是想扩展我编写代码的知识，所以如果你知道有一种更雄辩的方式来写这个，请告诉我。:)

不确定“使 a 和 b 对应”是什么意思，但也许这会起作用：

from itertools import permutations
from random import choice

globs = [glob.glob("DDtest/targetimagelist1/*"),
         glob.glob("DDtest/distractorimagelist1/*"),
         glob.glob("DDtest/targetimagelist2/*"),
         glob.glob("DDtest/distractorimagelist3/*"),
         glob.glob("DDtest/targetimagelist4/*")]

glob_permutations = list(permutations(globs))

a, b, c, d, e = choice(glob_permutations)

内置itertools库具有不重复排列的功能：

#!/usr/bin/env python2
import itertools
import glob

p = [
    glob.glob("DDtest/targetimagelist1/*"),
    glob.glob("DDtest/distractorimagelist4/*"),
    glob.glob("DDtest/targetimagelist2/*"),
    glob.glob("DDtest/distractorimagelist3/*"),
    glob.glob("DDtest/targetimagelist4/*"),
]

perm = itertools.permutations(p)

print(len(perm))

=> 120 个排列

也许是这样？

setup = {'1': ('1','1','2','3','4'),
         '2': ('1','1','2','3','4'),
        #...
        }
a = glob.glob("DDtest/targetimagelist" + setup[condition][0] + "/*")
b = glob.glob("DDtest/distractorimagelist" + setup[condition][1] + "/*")
c = glob.glob("DDtest/targetimagelist" + setup[condition][2] + "/*")
d = glob.glob("DDtest/distractorimagelist" + setup[condition][3] + "/*")
e = glob.glob("DDtest/targetimagelist" + setup[condition][4] + "/*")
