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))
