python - 在 Python 中以随机大小的部分拆分数字

Question

我有 x = 10 和 y = 100。

我可以将 y 元素随机分配给 x “元素持有者”吗？

我想创建 x 个类别，每个类别都有随机数量的项目；但是，创建的项目数应该正好是 y。

我猜是这样的

# number of categories and items
x = 10, y = 100

# keep track of how many items we have left to add
y_left = y

# create all categories
for i in range(x):
    # create category

    # find number of items in this category
    num_items_in_category = random.randint(1, y_left)

    # create items
    for j in range(num_items_in_category):
        # create item

    # set new number of items left to add
    y_left -= num_items_in_category

这其实并不难。让我们创建我们的容器:

import random

num_containers = 10
num_objects = 100

containers = [[] for _ in range(num_containers)]
objects = (some_object() for _ in range(num_objects))
# we don't need a list of these, just have to iterate over it, so this is a genexp

for object in objects:
    random.choice(containers).append(object)
