Example analysis of Python3.x operations on JSON

I have been learning python3 recently and happened to encounter some json operations. I simply compiled them and shared them. The following article mainly introduces you to some operations on JSON in Python3.x. Friends who need it can refer to it. The following is Come and learn with me.

Preface

This article mainly introduces you to some operations on JSON in python3, and shares them for your reference and study. Not much to say below. Having said that, let’s take a look at the detailed introduction.

1. Convert Dictionary to JSON

Convert dict to JSON, here use the package json

import json
aItem = {}
aItem["id"] = "2203"
aItem["title"] = "title"
aItem["subTitle"] = "sub title"
bItem = {}
bItem["id"] = "2842"
bItem["title"] = "b标题"
bItem["subTitle"] = "b副标题"
bItem["content"] = "内容"
bItem["list"] = ["a", "a 2", "b", "bb"]
aJson = json.dumps(aItem)
bJson = json.dumps(bItem, ensure_ascii=False)
print(aItem)
print(aJson)
print(bJson)

When it comes to Chinese characters, you need to specify ensure_ascii=False

Output:

{'id': '2203', 'title': 'title', 'subTitle': 'sub title'}
{"id": "2203", "title": "title", "subTitle": "sub title"}
{"id": "2842", "title": "b标题", "subTitle": "b副标题", "content": "内容", "list": ["a", "a 2", "b", "bb"]}

2. Convert list to JSON

Continue the above code

##

jsonList = []
jsonList.append(aItem)
jsonList.append(bItem)
jsonArr = json.dumps(jsonList, ensure_ascii=False)
print(jsonArr)

[{"id": "2203", "title": "title", "subTitle": "sub title"}, {"id": "2842", "title": "b标题", "subTitle": "b副标题", "content": "内容"}]
