Understanding Python super() with init() methods
The super()
function is used to call a method from a parent class. When used with the __init__
method, it allows you to initialize the attributes of the parent class, in addition to any attributes defined in the child class.
For example, if you have a parent class Person
with an __init__
method that sets the name attribute, and a child class Student
that inherits from Person
and has its own __init__
method that sets the student_id
attribute, you can use super()
to call the __init__
method of the parent class and set the name attribute while also setting the student_id attribute in the child class:
class Person:
def __init__(self, name):
self.name = name
class Student(Person):
def __init__(self, name, student_id):
super().__init__(name)
self.student_id = student_id
When you create a new Student
object, the __init__
method of the parent class Person
is called first to set the name attribute, and then the __init__
method of the child class Student
is called to set the student_id attribute.
It is important to note that the super()
call must be made after any attribute assignments in the child class, so that the attributes from the parent class are initialized before the child class modifies them.
