第十四节 python对象和json对象转换

 1 import json
 2 
 3 
 4 a = [{'a':1},{'b':'张三'}]
 5 b = json.dumps(a)
 6 
 7 # with open('a.json','w',encoding='utf-8') as fp:
 8 #     # fp.write(b)
 9 #     #json内置函数直接写入
10 #     json.dump(a,fp,ensure_ascii=False)#a是文件名,如果有中文ensure_ascii=False，不然会以Unicode的编码存储
11 # # json_str = '[{"a": 1}, {"b": "张三"}]'
12 # p_str = json.loads(json_str)
13 # for x in p_str:
14 #     print(x)
15 # with open('a.json','r',encoding='utf-8') as fp:
16 #     x = json.load(fp)
17 #     for y in x:
18 #         print(y)
