Python Job Payroll management System (third week)

Job Content:

Implementation results:

Read employees and their payroll information from the Info.txt file, and finally write the revised or increased employee payroll information to the original Info.txt file.

Effect Demo:

1. Check the employee's salary

2. Revise employee's salary

3. Add new Employee Records

4. Exit

Ideas:

File reading and writing, read or write data using the Strip and split method, the contents of the file to increase the search

Flowchart: (Pending update)
