Classes in python

A mold is an object that always produces elements of the same shape. In the same way a class is a container which allows to create elements of the same form called objects. As we can create a cake from a mold, we can also create objects (class instances) from a class. A class can have properties that describe it and method that give it behavior.

class student_info:
    """
    This class contains necessary informations about a student
    """
    
    student_id = ""
    firstname = ""
    lastname = ""
    grade = ""
    school = ""
    faculty =""

    def __init__(self,s_id,fn,ln,grade, sh, fa):

        self.student_id = st_id
        
    def set_firstname(self,firstN):
        self.firstname = firstN
        
    def set_lastname(self,lastN):
        self.lastname = lastN
        
        
    def set_grade(self,grad):
        self.grade = grad

Illustration: we create two instances of class student

in: stud1 = student_info("DI2122S82","Adama", "wilson", 5, "dataInsight","computer science")
stud2 = student_info("DI2122S04", "Traore", "Lucas", 2, "DataInsight", "Mathematics")

we get some information about stud1

in: stud1.get_student_id(), stud.get_school(), stud.get_faculty(), stud.get_firstname(), stud.get_lastname()

out: ('DI2122S82', 'dataInsight', 'computer science', 'Adama', 'wilson')

We modify the id of stud1

in: stud1.set_student_id("DI212265")

Access to the new id of stud1

in: stud1.get_student_id()

out: 'DI212265'
