In this article, we share the example of Python to achieve the specific code of the employee information management system for your reference, the specific content is as follows
1. Staff Information Management System
Request:
1、Enter each employee's information from the keyboard in turn, including name, employee id, ID number;
2. The eighteen digits of the ID number require that all but the 18th digit can be x, and the rest can only be numbers;
3. id shall consist of 5 digits;
4. Otherwise, the user is prompted to re-enter those items that do not conform to the rules;
5, can always view the entered employees and their information;
Tip:
1, string.isdigit () can determine whether the string is all numbers;
2、if String[-1] in "xX" Judge whether the last one is x or X;
3, each staff information can be saved in a dictionary, and then added to a staff list for management, if you want to view, traverse the staff list can be;
Reference Interface:
