Question

因此，我正在使用webscrapper从网站上获取有关运动鞋的信息。返回的子数据的结构如下

Dressed primarily in black nubuck with a reflective 3M layer underneath, the mid-top features Infrared accents on the midsole, heel tab and lace lock. Nike Air branding adorns the heel and sockliner, an OG detail last seen on the 2000 retro.",

Similar to the first release, the ‘Triple White’ 2018 model features a Primeknit upper, a Boost midsole and custom adidas and Yeezy co-branding on the insole.",

但是，我想更改它，以便顶层节点是运动鞋，而下一层则是特定的运动鞋品牌（乔丹，耐克，阿迪达斯），然后是该品牌的运动鞋列表。所以我的JSON结构看起来像这样

Sneakers {
Adidas :{
[shoe1,
 shoe2,
 ....

] },
Jordan: {
[shoe1,
 shoe2,
 ....

]
}
}

我不确定我可以使用哪种工具来做到这一点。任何帮助将不胜感激。目前，我所拥有的只是JSON文件，它不在我想要的结构中。

Answer 1

一种执行此操作的方法是填充一个dict，其键为品牌名称，其值为运动鞋记录列表。假设data是您的原始列表，则代码如下：

sneakers_by_brand = {}

for record in data:
    if sneakers_by_brand.get(record.get("brand")):
        sneakers_by_brand[record.get("brand")].append(record)
    else:
        sneakers_by_brand[record.get("brand")] = [record]

print(sneakers_by_brand)

改变JSON结构
