Python Classes

In advanced level Python programming, Python classes play a significant role. Python classes allow us to create objects. Each object has the potential to depict some real-life people or objects. When you write a class, basically you are describing how an object should behave when you set it to automation. You can create further objects in the Python classes. Each object tends to adopt the behavior that you describe in the class. The process of creating objects from classes is dubbed as instantiation. You have to manipulate instances. For example, you will have to decide which type of information you want your objects to use and perform tasks. You can store the information in the instances you create in a particular class. In addition, you can define certain actions that you want your objects to take. Two or more classes can also take the same code and do similar tasks. Classes are usually stored in modules. After that, you can import classes that are written by different programmers for your own programs. So, classes are portable that makes them more attractive and efficient to use. Classes are something that makes up the real code. When you start writing code to create classes, you will have the taste of being a programmer. You will know your code and you will be to maneuver around it to make it more efficient. In addition, you will be able to read and understand other programmer’s work.

Let’s start by creating a Python class. I will create a bird that could fly and feed his kids. We will define the type of bird and its color. After that, we will fill the class with the actions that we the bird to take. The Python class will tell the shell about how a bird looks and how it acts. After writing the main class, we will add the instances we want the class to integrate. In each instance, we will create different birds. Let’s see how to create an object and make it move.

The Bird Class

Let’s write the code to create the bird class. We will need variables that could store information like the type of the bird and its color. After that, we will move on to big things.

class Bird():

"""I am creating a bird with the help of Python classes"""

def __init__(self, name, color):

"""Now we have to initialize the name and color of the bird"""

self.name = name

self.color = color

def fly(self):

"""this will make the bird fly in the air up above the sky."""

print(self.name.title() + " is flying in the air.")

def feed(self):

""" This will make the bird feed the little ones."""

print(self.name.title() + " is now feeding the birds!")

my_bird = Bird('Parrot', 'Green')

print(my_bird.name.title() + " is flying in the air.")

print(my_bird.color.title() + " lovely " + my_bird.name.title() + " is now feeding the birds!")

$python main.py

Parrot is flying in the air.
