Question

目前我的代码返回客户端的名称和visit_length的随机值。我希望它返回客户名称，然后返回visit_length中的一个或多个元素，即("Client 1", 15, 45), ("Client 2", 45, 60), ("Client 3", 30)

N = 20      
randomitems = []
visit_length = [15, 30, 45, 60]
value_range = np.arange(0, N, 1)

for i in value_range:
    visits = ("Client %d" % i, random.choice(visit_length))
    randomitems.append(visits)

有什么建议吗？我以为随机库中可能有东西，但我还没有找到任何东西。

谢谢！

选择要随random.randint追加的项目的随机数visit_length，然后将import random import numpy as np N = 20 randomitems = [] visit_length = [15, 30, 45, 60] value_range = np.arange(0, N, 1) for i in value_range: k = random.randint(1, len(visit_length)) visits = ("Client %d" % i,) + tuple(sorted(random.sample(visit_length, k=k))) randomitems.append(visits)中的元素数量与random.sample一起使用。

import random
import numpy as np

N = 20
MAX_VISIT_LENGTHS = 4  # You can choose as many as you want now I guess
randomitems = []
visit_length = [15, 30, 45, 60]
value_range = np.arange(0, N, 1)

for i in value_range:
    k = random.randint(1, MAX_VISIT_LENGTHS)
    vs = sorted(random.choice(visit_length) for _ in range(k))
    # If you do not want to sort use
    # vs = [random.choice(visit_length) for _ in range(k)]
    visits = ("Client %d" % i,) + tuple(vs)
    randomitems.append(visits)

如果您想允许重复的项目：

echo "c:\tmp\$(TestCaseID)\$(repoZipExtractedName)\windows_downloader.bat -
    configFile c:\tmp\$(TestCaseID)/$(OfflineDownloader_FileName)" > //$(repoServer)/c/tmp/$(TestCas  eID)/execute.bat

更新回答以返回元组

我可能误解了你想要的东西，但这是我对这个问题的看法：我们创建一个函数，从列表x返回一个随机数量的项目（在1-4 = N之间）并以随机顺序返回它们。

import random

def visits_func():
    N = random.randint(1, 4)
    x = [15, 30, 45, 60]
    y = []
    while N:
        y.append(x.pop(random.randrange(len(x))))
        N -= 1
    return y

value_range = range(1,6) #1,2,3,4,5,6

randomitems = []

for i in value_range:
    visits = tuple(["Client %d" % i] + sorted(visits_func()))
    randomitems.append(visits)

打印，例如

[('Client 1', 15, 60),
 ('Client 2', 15),
 ('Client 3', 45, 60),
 ('Client 4', 30, 60),
 ('Client 5', 15, 30, 45)]

如何从列表中返回一个或多个项目？
