python - 任何帮助，在从 HTML 解析 JSON 时卡住我的代码。需要告诉我库存何时为真

问题描述

我在 HTML 中有这个 JSON 输出，我想检查库存。我已经构建了所有东西，但是当 Python 需要告诉我库存是否真实时，我陷入了困境。

所有数字都是荷兰各地的商店。如果其中只有一个是 TRUE，我只想编写 Python 打印“In Stock”的代码。我做了'' if ... or ... == 'True'，但是如果其中一家商店是假的，它告诉我它仍然缺货。

知道我需要使用什么样的代码让 Python 告诉我其中一家商店是否有库存吗？

我正在使用 BS4，Beautifulsoup 来解析 JSON。

只是停留在 ''If... == 'True' 部分。

谢谢！

任何是一个测试，不熟悉它......

解决方案

如果你有那么多手动输入，每个都做同样的事情，你的代码就会失控。首先，我建议列出产品代码

products = [193, 194, 360, 384, ...]

来自 js 的 response.json() 不是你在 python 中使用的。首次进口

import json

然后分别使用 json.loads() 或 json.dumps() 来“解析”和“字符串化”

store = json.loads(<soup.whatever>)

然后我假设“1665134”是商品 id 或其他东西，您可以遍历后续对象

for product in store:
    if(product['hasStock']):
        # do stuff with stock
    else:
        # has no stock, you're sol
