Python JSON操作

Python JSON操作

Json文件读写

• dumps()：将dict数据转化成json数据（Python里是str类型）
• loads()：将json数据转化成dict数据（Python里是dict类型）
• load()：读取json文件数据，转成dict数据
• dump()：将dict数据转化成json数据后写入json文件

import json
def dict_to_json():
    dict1={}
    dict1['name']='tom'
    dict1['age']=20
    dict1['sex']='male'
    print(dict1)
    jsons=json.dumps(dict1)
    print(jsons)
    print(type(jsons))

def json_to_dict():
    jsons = '{"name": "tony", "age": 28, "sex": "male", "phone": "123456", "email": "loadkernel@126.com"}'
    dict1= json.loads(jsons)
    print(dict1)
    print(type(dict1))

def dict_to_json_write_file():
    dict = {}
    dict['name'] = 'tom'
    dict['age'] = 10
    dict['sex'] = 'male'
    print(dict)
    with open('test.json', 'w') as f:
        json.dump(dict, f)

def json_file_to_dict():
    with open('test.json', 'r') as f:
        dict1 = json.load(f)
        print(dict1)
        print(type(dict1))

if __name__ == '__main__':
    dict_to_json()
    json_to_dict()
    dict_to_json_write_file()
    json_file_to_dict()
