python str 轉換 json

使用Python編碼和解析Json

Python內置了json包來幫助咱們完成對json的操做。

針對str操做：將Python的字典結構導出到json使用json.dumps() ，將json讀成Python的字典結構，使用json.loads() 。

針對對文件操做：分別使用json.load()函數和json.dump()函數。

# coding=gbk
import traceback
import json
file_name = '廣州市_農貿市場_1717.txt'
f = open(file_name, 'r')
tmp = json.load(f)
print(type(tmp))
data = []
for i in tmp:
#    print(i)
#測試作一下格式轉換
    dl = {
        "name":i["name"],
        "location_lat" : i["location"]["lat"],
        "location_lng" : i["location"]["lng"]
    }
    data.append(dl)
print(data)
with open('ceshi.txt', 'w', encoding="utf-8") as f:
    f.write(json.dumps(data, ensure_ascii=False))
    print('---wirte success---')
