Understanding Python super() with init() methods
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.
