何为pyhs？简单来说，就是封装了接口，实现python以nosql方式连接mysql数据库，对数据库进行一些操作。

pyhs is a pure Python client (with optional C speedups) for HandlerSocket plugin to MySQL database. In short, it provides access to the data omitting the SQL engine in a NoSQL-like interface. It allows all simple operations (get, insert, update, delete) over indexed data to perform considerably faster than by usual means.

进入主题，在update操作时，使用变量是没错的：

 1 from pyhs import Manager

 2 

 3 attendant_id = '222'

 4 newname = 'wxb'

 5 newpwd = '123456'

 6 

 7 hs = Manager()

 8 name = '2a'

 9 

10 data=hs.update('final','kf_attendant','=',['AD_ID','AD_Name','AD_Password'],[attendant_id],[attendant_id,newname,newpwd],None,1,0,True)

但是进行insert操作时，直接使用变量名就一直出错“SystemError: NULL result without error in PyObject_Call”，结果使用str()函数解决了~

 1 from pyhs import Manager

 2 import uuid

 3 

 4 hs = Manager()

 5 

 6 newid = uuid.uuid1()

 7 newname = 'aaa'

 8 newpwd = '123'

 9 

10 hs.insert('final','kf_attendant',[('AD_ID',str(newid)),('AD_Name',str(newname)),('AD_Password',str(newpwd))])
