python - 在 Python 中解析 Json 并找到一个值

问题描述

我正在尝试使用 Python 和 json 库解析以下 Json

{"attributes":{"173":{"id":"173","code":"Size","label":"Size","options":[{"id":"352","label":"Footwear-41","products":["78834"]},{"id":"355","label":"Footwear-42","products":["78835"]},{"id":"357","label":"Footwear-42.5","products":["78836"]},{"id":"358","label":"Footwear-43","products":["78837"]},{"id":"361","label":"Footwear-44","products":["78838"]},{"id":"363","label":"Footwear-44.5","products":["78839"]},{"id":"364","label":"Footwear-45","products":["78840"]},{"id":"367","label":"Footwear-46","products":["78841"]}],"position":"0"}},"template":"<%- data.price %>\u00a0 \u20ac","currencyFormat":"%s\u00a0 \u20ac","optionPrices":{"78834":{"oldPrice":{"amount":189.9},"basePrice":{"amount":159.57983093277},"finalPrice":{"amount":189.9},"tierPrices":[]},"78835":{"oldPrice":{"amount":189.9},"basePrice":{"amount":159.57983093277},"finalPrice":{"amount":189.9},"tierPrices":[]},"78836":{"oldPrice":{"amount":189.9},"basePrice":{"amount":159.57983093277},"finalPrice":{"amount":189.9},"tierPrices":[]},"78837":{"oldPrice":{"amount":189.9},"basePrice":{"amount":159.57983093277},"finalPrice":{"amount":189.9},"tierPrices":[]},"78838":{"oldPrice":{"amount":189.9},"basePrice":{"amount":159.57983093277},"finalPrice":{"amount":189.9},"tierPrices":[]},"78839":{"oldPrice":{"amount":189.9},"basePrice":{"amount":159.57983093277},"finalPrice":{"amount":189.9},"tierPrices":[]},"78840":{"oldPrice":{"amount":189.9},"basePrice":{"amount":159.57983093277},"finalPrice":{"amount":189.9},"tierPrices":[]},"78841":{"oldPrice":{"amount":189.9},"basePrice":{"amount":159.57983093277},"finalPrice":{"amount":189.9},"tierPrices":[]}},"priceFormat":{"pattern":"%s\u00a0 \u20ac","precision":2,"requiredPrecision":2,"decimalSymbol":",","groupSymbol":".","groupLength":3,"integerRequired":1},"prices":{"oldPrice":{"amount":189.9},"basePrice":{"amount":159.57983093277},"finalPrice":{"amount":189.9}},"productId":"78842","chooseText":"Choose an Option...","images":[],"index":{"78834":{"173":"352"},"78835":{"173":"355"},"78836":{"173":"357"},"78837":{"173":"358"},"78838":{"173":"361"},"78839":{"173":"363"},"78840":{"173":"364"},"78841":{"173":"367"}},"sku":{"default":"CI6400-100","78834":"CI6400-100-Footwear-41","78835":"CI6400-100-Footwear-42","78836":"CI6400-100-Footwear-42.5","78837":"CI6400-100-Footwear-43","78838":"CI6400-100-Footwear-44","78839":"CI6400-100-Footwear-44.5","78840":"CI6400-100-Footwear-45","78841":"CI6400-100-Footwear-46"},"stock":{"78834":{"is_salable":true,"qty":1},"78835":{"is_salable":true,"qty":2},"78836":{"is_salable":true,"qty":3},"78837":{"is_salable":true,"qty":3},"78838":{"is_salable":true,"qty":3},"78839":{"is_salable":true,"qty":1},"78840":{"is_salable":true,"qty":3},"78841":{"is_salable":true,"qty":1}}}

我想获得特定鞋码尺寸的“产品”价值，例如。如果我想要 42，请找到 78835。

我尝试通过两种方式做到这一点：

1.

tex=THEJSONTEXT
jsn=json.loads(tex)
jsn['attributes']['173'].get("products","")

但这对我不起作用。所以我尝试了第 2 版：

import re
prod=re.findall('"Footwear-42","products":["\d\d\d\d\d"]', tex)

甚至这对我也不起作用....

解决方案

实际上还有一层嵌套。试试下面的。

for i in jsn['attributes']['173']["options"]:
    print(i["products"])

也是options一个列表。
