Inheritance in Python. Inheritance is one of the most important aspects of Object Oriented Programming. Using Inheritance a class can reuse components of another class by inheriting it.
Variable f is again declared in function and assumeslocalscope. It is assigned value “I am learning Python.” which is printed out as an output. This variable is different from the global variable “f” define earlier Once the function call is over, the local variable f is destroyed. At ...
Python access modifiers play an important role to protect the data from unauthorized access. When inheritance is implemented there is a huge risk for the data to get destroyed due to the transfer of unwanted data from the parent class to the child. That is why the access modifier is used. ...

Multiple inheritance is a touchy subject. In principle, it's very simple: a subclass that inherits from more than one parent class is able to access functionality from both of them. In practice, this is less useful than it sounds and many expert programmers recommend against using it....

In multilevel Inheritance, one or more class act as a base class. Which means the second class will inherit the properties of the first class and the third class will inherit the properties of the second class. So the second class will act as both the Parent class as well as Child class...
