json模块的简单操作

#单行操作
import json
import time

#json dumps操作，将python对象转换为json对象

d = {
    '谦谦': {
        'sex': '男',
        'addr': '北京',
        'age': 34
    },
    '千千': {
        'sex': '女',
        'addr': '北京',
        'age': 34
    },
    'name': 'test',
    '爱好': '吃饭睡觉打豆豆'
}
d_dumps = json.dumps(d, ensure_ascii=False, indent=4)
with open('test_json_01.json', 'a+', encoding='utf-8') as f:
    f.write(d_dumps)

time.sleep(2)
#loads
with open('test_json_01.json', 'r+', encoding='utf-8') as f_01:
    f_01_file = f_01.read()
    f_01_file_dic = json.loads(f_01_file)
    print(f_01_file_dic)

 

#多行，换行的操作参考
import json
import time

#json dumps操作，将python对象转换为json对象

d = {
    '谦谦': {
        'sex': '男',
        'addr': '北京',
        'age': 34
    },
    '千千': {
        'sex': '女',
        'addr': '北京',
        'age': 34
    },
    'name': 'GGG',
    '爱好': '吃饭睡觉打豆豆'
}
d_dumps = json.dumps(d, ensure_ascii=False) + '\n'
with open('test_json_01.json', 'a+', encoding='utf-8') as f:
    f.write(d_dumps)
    f.write(d_dumps)
    f.write(d_dumps)
    f.write(d_dumps)
    f.write(d_dumps)  #如果是多行要注意loads是readline或者readlines

time.sleep(3)
#loads
with open('test_json_01.json', 'r+', encoding='utf-8') as f_01:
    f_01_file = f_01.readlines()
    for i in f_01_file:
        i_dic = json.loads(i)
        print(i_dic)
