Python怎么读写json格式文件

import jsonwith open('data.json') as data_file: data = json.load(data_file)# do something with data

#读 file = 'test.json' fp = open(file, 'r') dict = json.dump(fp.read()) fp.close() #写 testDict = {'a':1,'b':2} file = 'my.json' fp = open(file,'w+') fp.write(json.loads(testDict)) fp.close()

# coding=utf-8import json#写testDict = {'a':1,'b':2}file = 'test.json'fp = open(file,'w+')fp.write(json.dumps(testDict))fp.close()#读file = 'test.json'fp = open(file, 'r')dict = json.loads(fp.read())print dictfp.close() 这段你...

import json# readf = open('x.json', 'r')s = f.read()f.close()o = json.loads(s)# writeo['name'] = 'xx's = json.dumps(o)f = open('y.json', 'w')f.write(s)f.close()

#读 file = 'test.json' fp = open(file, 'r') dict = json.dump(fp.read()) fp.close() #写 testDict = {'a':1,'b':2} file = 'my.json' fp = open(file,'w+') fp.write(json.loads(testDict)) fp.close()

以下示例展示基于Python3.x的json文件的读写: def json_basic(): """json基本操作""" import json data = { "ID": 1, "课程": "Python", "机构": "优品课堂", "单价": 200.00 } json_str = json.dumps(data) print(json_str) json_data = json....

import jsonf=open('name_list.json')json.load(f) #读取

f=open('aaa.txt','a')json.load(f) #读取json.dump('qqq',f) #将字符串qqq写入到f中f.close()

例如jsonstr='{"d":"1","v":"2"}' import json dict = json.loads(jsonstr) json=>dict dict[q] = 3 jsonstr = json.dumps(dict) dict=>json

#读file = 'test.json'fp = open(file, 'r')dict = json.dump(fp.read())fp.close()#写testDict = {'a':1,'b':2}file = 'my.json'fp = open(file,'w+')fp.write(json.loads(testDict))fp.close()更详细的说明可以参考这篇博文: http://www.tuic...
