PythonAdd __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 thepass 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 theStudent class:
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__() functionoverrides 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
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.
