# 1. 使用eval()或exec()函数实现 | |
eval_user_info = eval(user) | |
print eval_user_info | |
exec('exec_user_info=' + user) | |
print exec_user_info | |

# 2.这种字符串是典型的JSON格式,最好使用simplejson把JSON转化为Python内置类型 | |
import simplejson | |
# JSON转化为字典 | |
json_2_dict = simplejson.loads(user) | |
print json_2_dict | |
#字典转化为JSON字符串 | |
dict_2_jsonstr = simplejson.dumps(json_2_dict) | |
print dict_2_jsonstr |
