W29--python01-字典与字符串互转，列表和元组可以互转

# json字符串处理为字典

json_s = '[{"status":401,"msg":"用户名密码错误","st":true}]'

print(json_s)

# 处理成字典？

import json

json_dict = json.loads(json_s)

print(json_dict)

# 字典转json字符串

json_dict = {'status': 401, 'msg': '用户名密码错误', 'st': True}

json_s = json.dumps(json_dict)

print(json_s)

# 列表和元组可以互转

my_tup = ('name', 'will')

my_tup[0]

使用场景，全局变量

my_list = list(my_tup)

print(my_list)

print(tuple(my_list))
