• Getting values from JSON using Python 5个答案

我有这个字符串，但我需要从字符串/ json中提取特定的值。

{"Artigo":{"NrReg":"81846","Cod":"XXX96000051","Desc_Web":"XX 296 00 BLACK","Desc_Agregadora":"XX 296","PVO":"69","NlDes":"3","Cat1_GrpArtigos":"\t2","Cat2_SegMarca":"s\t0","Cat3_SegAcessorios":{},"Cat4_Categoria":{},"Marca":{},"Attr_Sexo":{},"Attr_MatGenerico":{},"Attr_TipoOculo":{},"Profile_V":"1","Profile_S":"0","StockQty":"0","Image":"XXX96000051.jpg","ImageF":{}}}

我在Python 3.7中使用此代码从URL中提取此字符串，然后我需要获取一些值，例如“Cod”是“XXX96000051”

码：

import requests
import time
import json

url = "http://www.urlsite.test"
data = requests.get(url)
result = data.json()


print(result)
t0 = time.time()

for i in result:
    print(i[0])

print("Total time " + str(time.time() - t0) + " sec")

您应该通过键访问dict的值，因此要获取密钥Cod的值，密钥Artigo嵌套在密钥result['Artigo']['Cod'] 下，您应该使用：
