Python Add __init__() Function
Add the __init__() Function
So far we have created a child class that inherits the properties and methods from its parent.
We want to add the __init__() function to the child class (instead of the pass keyword).
Note: The __init__() function is called automatically every time the class is being used to create a new object.
Example
Add the __init__() function to the
Student class:
class Student(Person):
def __init__(self, fname, lname):
#add properties etc.
When you add the __init__() function, the child class will no longer inherit
the parent's __init__() function.
Note: The child's __init__()
function overrides the inheritance of the parent's
__init__() function.
To keep the inheritance of the parent's __init__()
function, add a call to the
parent's __init__() function:
Example
class Student(Person):
def __init__(self, fname, lname):
Person.__init__(self, fname, lname)

Now we have successfully added the __init__() function, and kept the
inheritance of the parent class, and we are ready to add functionality in the
__init__() function.
