python 大量使用json 存储数据时，格式化输出的方式

import json, pprint

dic = {'name': 234, 'user_name': 'yan xia ting yu ', 'list': ['ds', 'a', 2], '你好这是键': '檐下听雨'}
print(dic)
pprint.pprint(dic)
print(json.dumps(dic))
print(json.dumps(dic, indent=2))

# {'name': 234, 'user_name': 'yan xia ting yu ', 'list': ['ds', 'a', 2], '你好这是键': '檐下听雨'}
# {'list': ['ds', 'a', 2],
#  'name': 234,
