Why there is no switch statement in python? - tccicomputercoaching.com

Switch case is a powerful decision-making construct commonly used in modular programming .

Unlike other programming languages, Python doesn’t provide a switch case instrument over the self.

However, it has many other constructs like a dictionary, lambda function, and classes to write a custom implementation of the Python switch case statement.

One example of Switch in Python :

Here, we define a function week() to tell us which day a certain day of the week is. A switcher is a dictionary that performs this mapping.

As you can see, for values other than the ones we mention in the switcher, it prints out “Invalid day of week”. This is because we tell it to do so using the get() method of a dictionary.

What is Inheritance? tccicomputercoaching.com

Inheritance is a feature of Object Oriented Programming . It is used to specify that one class will get most or all of its features from its parent class. It is a very powerful feature which facilitates users to create a new class with a few or more modification to an existing class. The new class is called child class or derived class and the main class from which it inherits the properties is called base class or parent class.

The child class or derived class inherits the features from the parent class, adding new features to it. It facilitates re-usability of code.

Python Inheritance Syntax

baseclass as per previous example

1. class DerivedClassName(BaseClassName):
2. <statement-1>
3. .
4. .
5. .
6. <statement-N>

Here we always use object of parent type.

object=baseclass()

This child type object will call both module of parent and child.
