如何在python中从json文件读取json对象数组

Question

我有一个名为example.json的json文件，包含以下内容

[{
 "product/productId" : "XXX",
  "product/title" : "14k Yellow Gold Butterfly Pendant, 16 ",
  "product/price" : "unknown",
  "review/userId" : "XXX",
  "review/profileName" : "Disappointed Sony customer",
  "review/helpfulness" : "1/1",
  "review/score" : "4.0",
  "review/time" : "1178150400",
  "review/summary" : "pretty necklace",
  "review/text" : "It is a nice made necklace, and the butterfly pendant looks beautiful. I love it.",
 "numOfPositive" : "2",
 "numOfNegative" : "0"
},
{ "product/productId" : "XXXX",
  "product/title" : "14k Yellow Gold Butterfly Pendant, 16 ",
  "product/price" : "unknown",
  "review/userId" : "TTT",
  "review/profileName" : "A. Thorpe  Amazon lover ",
  "review/helpfulness" : "1/1",
  "review/score" : "4.0",
  "review/time" : "1175990400",
  "review/summary" : "pretty necklace",
  "review/text" : "I bought this necklace on a whim; I love butterflies and it looked so dainty anadfasdfasdfd sweet. It was actually a little more weighty than I expected, although it's not a solid piece. The chain is shiny and nicer than I expected.",
 "numOfPositive" : "4",
 "numOfNegative" : "0"
}]

意思是-文件包含由“，”分隔的文件分配。 如何在python中分别读取和处理每个json文档（将其发送到rest api）？ 附笔 原始文件可以有几个GB的大容量

用任何文本编辑器打开文件。在文件的开头添加一个[，在结尾添加一个]。这将把您拥有的数据转换为实际有效的JSON数组。

然后使用json module来处理它。

import json
arr = json.loads("example.json")
# Do nifty stuff with resulting array.
