Project: School Manager

This project aims students to prepare for a understanding of core python features and an object oriented programming.

prerequisites:

• json module
• Object-Oriented programming, File handling, and Exception handling.

Create a software that keeps record of students in a file. The software should initialize when it is executed from the file main.py.

The folder structure should be as follows:

📂project/
├── 📂records
│   ├── 📜grade1.json
│   ├── 📜grade2.json
│   └── 📜grade3.json
│
├── 🐍main.py
└── 📜log.txt

main.py File

This file should contain 2 classes Grade, and Student.

The class Student should have the following attributes:

• first_name: str public instance attribute
• lase_name: str public instance attribute
• roll: int public instance attribute
• age: int public instance attribute
• major: computer or math or science
• get_full_name(): public method
• __str__()

The class Grade should have the following attributes:

• name: str (public instance attribute)

• students: List[Student] (public instance attribute)

• list_students: function this should show all the students in the tabular format. The output should be of the following format:

  ------------------------------------
  Roll  Full Name   Age     Major
  ------------------------------------
    1   Jon Doe      20     Math
    2   Jane Doe     22     Science
    3   Jin Doe      19     Computer
  ------------------------------------
  

  Hint for columns length

  • Roll: 5 (justify Right)
  • Full Name: 40 (Justify Left)
  • age: 3 (Justify Right)
  • Major: 20 (Justify Left)

  You can use column spacing of 2 if you want.

• add_student(): function that adds a student with all detail entered in the console.

• remove_student(roll) function that takes the roll number and removes the student with the roll number specified.

  Add more as per your interests.

• Use json library for storing contents to the json file.

}

Bonus Options:

• you can create a different module for Student and Grade classes and import in the main.py file.
• You can password protect your classes so that whenever someone tries to access the class, they need to enter the password.
• you can try saving hashed password using some hashing or encryption methods.
• you can use file formats other than json Eg: XML, or csv file.
