python3.0怎么用json从文件解析

1、说明:python3通过json模块load函数来解析文件。2、代码示例:首先编写一个json文件j.txt,内容如下:{"errno":1,"errmsg":"操作成功!","data":[]}python代码如下: import jsonwith open('j.txt', 'r') as fr: o = json.load(fr) print(o['e...

import jsonjsonfile = '/path/to/jsonfile'with open(jsonfile, encoding='utf8') as f: # utf8改成文件jsonfile对应的编码 result = json.load(f)

import jsons = json.loads('{"name":"test", "type":{"name":"seq", "parameter":["1", "2"]}}')print sprint s.keys()print s["name"]print s["type"]["name"]print s["type"]["parameter"][1]

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()

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()

下面给出一个使用python解析json的简单例子: #!/usr/bin/python import json #Function:Analyze json script #Json is a script can descript data structure as xml, #Note: #1.Also, if you write json script from python, #you should use ...

#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()

#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()
