Simple Student Management System Using Python and Files

This is the fourth post in a series of mini-projects for Python where you can learn programming knowledge related to python and implement them as a project. The project consists of a simple file-based student management system that maintains the records in the files. The CSV file is used to store the record as a comma-separated value.

The mini-project consists of the following features:-

1. Add New Student
2. View Students
3. Search Student
4. Update Student
5. Delete Student

To begin the implementation in Python, make sure you have the following tutorials covered:-

• Python Numbers
• Python Functions
• Python if…else Statement
• Python Class and Objects
• CSV Files in Python
