The main problem with extending a class is that you can’t change the behavior of the original class without affecting all of the instances of that class.
class BaseClass: def __init__(self): print "BaseClass __init__" class DerivedClass(BaseClass): def __init__(self): BaseClass.__init__(self) # call base class constructor print "DerivedClass __init__"
This code creates two classes, BaseClass and DerivedClass. BaseClass has a constructor that prints “BaseClass __init__”. DerivedClass also has a constructor that calls the BaseClass constructor and then prints “DerivedClass __init__”.
What is a class
A class in Python is a template for creating objects.
Extend classes in Python are a powerful feature that allow you to create custom classes that can be used in your code. This allows you to create custom objects that can be used in your code, and it also allows you to reuse code across different objects.
To create an extend class in Python, you first need to create a new class file. You can do this by opening up a new file in your editor, and then typing the following code:
def __init__(self, name):
self.name = name
