Prompt Title: Student Database Management System.

Sure, here's an example of object-oriented Python code that implements a student database system:

pythonCopy code
class Student:
    def __init__(self, name, age, gender, grade, address, parent_name, parent_phone):
        self.name = name
        self.age = age
        self.gender = gender
        self.grade = grade
        self.address = address
        self.parent_name = parent_name
        self.parent_phone = parent_phone
        self.attendance = {}
        self.grades = {}
        self.disciplinary_records = []

    def add_attendance(self, date, status):
        self.attendance[date] = status

    def add_grade(self, subject, score):
        self.grades[subject] = score

    def add_disciplinary_record(self, record):
        self.disciplinary_records.append(record)


class StudentDatabase:
    def __init__(self):
        self.students = []

    def add_student(self, student):
        self.students.append(student)

    def get_student_by_name(self, name):
        for student in self.students:
            if student.name == name:
                return student
        return None

    def get_student_by_grade(self, grade):
        grade_students = []
        for student in self.students:
            if student.grade == grade:
                grade_students.append(student)
        return grade_students
