Simple People Finder
Background
Every company has a database (or multiple databases) of its employees. In which, every employee’s information is stored in a well-designed structure. Managers can use this database to search employee information for different purposes (promotion, assignment, relocation, etc.).
To complete the python assignment, you will implement a system that can
- Load a data file that contains 1000 data entries.
- Provide users a feature to search people by their first name.
- Output the search result to the user.
In real-life, employee information should be stored in a database system that is very complex and secure. In this assignment, we are not going to implement that database system, but try to utilize the data structure we learned in the past 2 weeks, which is List.
For example, if the user wants to search records with the first name “Terry”, your program should provide the user with the following 2 records:
The user does not have to enter the data file name. Let’s say it is always by default a file named data.txt and it will always be put in the folder together with your program. Your program should continue asking for user input until the user types in “EXIT” or “exit”
