# -*- coding: UTF-8 -*-
def insert_sql(**kw):
   keys = []
   values = []
   for k in kw:
       keys.append(k)
       values.append(kw[k])
   SQL_INSERT = "insert into nostray%s values%s" % (tuple(keys),tuple(values))
   return SQL_INSERT
   # return SQL_INSERT


sql = insert_sql(userid="a", username="b", age='20')
print sql
