Little rookie of the Python learning Path----information Query system

Function Description:

(1) User authentication function, only enter the user name and password to query
(2) can check the employee's Id,name, department, telephone
(3) The query interface keyword is the name, the user through the name to check other related information.
(4) Check out the output user information, if the query fails, the report does not have this user, and then loop up

The Python source code is as follows (importing data by reading external files)
