Python use command word in the function -

i new in python.

this part of python web service(flask) code.

the function login uses command parameter,however; don't see other classes call login function.

my question : command here?

import mysqldb mydb  def login(command):     command = command[1:]     command = command[:-1]     command = command[15:]     = 0     while command[i] != ',':         = + 1     username = command[:i - 1]     command = command[i + 17:]     = 0     while command[i] != ',':         = + 1     password = command[:i - 1]     return queryuser(username, password)  def queryuser(username, password):     sdb = mydb.connect(host='127.0.0.1',user='root',passwd='1',db='testdb')     query = sdb.cursor()     query.execute("""select user_id user_info user_id = %s , user_password = %s""", (username,password,))     if query.fetchone() not none:         query.close()         sdb.close()         return 'true'     else:         query.close()         sdb.close()         return 'false: invalid username , password' 

my guess function imported module somewhere else in code base (or possibly flask automatically). code horribly unpythonic can tell, command string contains username , password, separated comma this:

login('????????????????awd,?????????????????1234cats,?????') → queryuser('awd', '1234cats')
