class inside class Python

The concept of having a Python class inside another class is known as an inner class.

Inner classes allow you to create classes within a class, which can help you to better organize and structure your code.

For example, you may want to create an inner class to represent a specific type of object that will be used within your main class.

Inner classes can also be used to create a collection of related methods or functions that can be accessed from the main class.

Ultimately, the use of inner classes can help to keep your code organized and more easily readable.

In Python programming, we can use the class to organize all the data.Β 

What is Python Class?

Python is an”object-oriented programming languageβ€œ.

When working with Python, you may expect that the majority of your code will be implemented using a unique concept known as Python classes.

A good way to think about classes is like a blueprint. They indicate that it must have a data-type appearance and list all the characteristics and features it must have.

One of the greatest things about Python is its capability to enable us to work together and keep an eye on a lot of data.

In reality, data is the driving force behind the programs that you will write. These kinds of data will pose a problem if we would like to write programs.

Why use classes in Python?

Classes in Python are a great way to organize and structure your code, making it easier to read and maintain.

Classes allow you to define objects that contain data as well as methods that can be used to manipulate that data.

By using classes, you can create objects that can help you to logically group and structure related data and functions together.

This helps to reduce the amount of duplicate code, making your programming more efficient and easier to maintain.

Classes can also help to keep your code organized and manageable for larger projects.

How to make a class in Python?

Developers use classes to keep things that are related. It can be done using the keyword class which is a group of object-oriented programming.

Developers use classes to keep related things together.

This can be done using the keyword β€œclass”  which is a group of object-oriented constructs.

So, let’s create a class for our Book:

class Book:
  def __init__(self, title, author, numPages):
      self.title = title = author
      self.numPages = numPages

Python class Method

The Python class Method has access to all of the information included in the instance of this object.

They could access and modify anything previously set on themselves.

In order to be used, They require an instance of the class.

Python Class Inside Class

You can create a class inside a class in Python using the β€œclass” keyword. To create a class within a class, you need to nest the inner class within the outer class.

The inner class can then access the attributes and methods of the outer class. Here is an example of how this works:

class OuterClass:
def __init__(self):
print("Outer class")

class InnerClass:
def __init__(self):
print("Inner class")

def inner_method(self):
print("This is the inner class method")

# create an instance of the OuterClass
outer = OuterClass()

# create an instance of the InnerClass
inner = outer.InnerClass()

# call inner_method()

Nested Classes in Python [inner class python]

An example is created that calls a method in the inner class:

class Body:

def __init__(self): = 'cute'
self.part = self.Hands()
class Hands:
def runner(self):
return 'running...'

if __name__ == '__main__':
cute = Body()
print cute.part.runner()

In the program above we have the inner class Hands() that has its own method.

An inner class can have both variables and methods. In this case, the constructor of this class Human (init) generates a new part object.

   class Body:
 Β  def __init__(self): = 'cute'
   self.part = self.Hands()
   self.everyw = self.Ball()

Β  class Hands:
   def movement(self):
   return 'movement continue...'
   class Ball:
   def straight(self):
   return 'flying...'

Β   if __name__ == '__main__':
   cute = Body()
   print cute.part.movement()
   print cute.everyw.straight()

By using Python inner classes you may make your code much more object-orientated.

A single object can hold several sub-objects. We can also use them to add more classes to our programs.

Here are a few resources that can help you get started:

  1. The Python documentation has a great guide on classes in Python:
  2. Here is a link to a StackOverflow answer that explains how to create a class inside a class in Python:
