Python Programming Language

What is Python?

What is Python Programming Language?

Python is a high-level programming language and it was developed by Guido van Rossum in 1991 and Python foundation. Since it was introduced, it has become a favorite of global software developers as it is designed with code readability, simpler syntax, and GUI support. The learning of Python programming language is very easy for beginners and experienced programmers. Here we give you some fundamental Python things that are useful for you to jump-start your career in software development.

Latest version of Python 3.10.1 is now available to download.

Applications of Python Programming Language

Python can be used in every field of development as it is general-purpose nature and developer-friendly programming language. Python is used in three major platforms for developing applications such as web development, data science process, and scripting development. Following are the detailed use cases of the Python programming language.


Console-based applications: Applications that run from command-line or shell scripting. Python has a REPL (Read-Eval-Print-Loop) feature for developing console-based applications. 

Business Applications: Applications for ERP and E-Commerce platforms. Python provides the Tryton platform with readability, scalability, and extensibility to create rich-featured business applications. 

Web Applications: Python has numerous powerful libraries such as Django, flask, Plone, and Django CMS to handle internet protocols such as XML, email processing, JSON, Feedparser, HTML that are used for developing web applications.

Enterprise Applications: Applications for customer relationship management and billing system. Python has various business tools to draw the model of the entire business process and it is used to create enterprise applications for the improvement of productivity and efficiency of businesses. 

Software Development Applications: Python supports greatly the development of testing control and management tools for SDLC processes. Scions are one of Python frameworks for developing build controls, Apache and Buildbot for automated testing, and Trac or Round for project management.

Desktop GUI Applications: Python has some useful libraries namely Tk GUI, Tkinter, Kivy, PyQT, PySide, and wxWidgetM for developing rich and smooth graphical user interfaces that interact effectively with users through visual indicators. 

3D CAD Applications: Python is very good for 3-D Computer-aided design that replaces manual drafting with an automation process. It helps architectural professionals for simplified engineering in 3-D mode using some of the popular functionalities of Python like RCAM, AnyCAD, CamVox, and Fandango.

Scientific and Numerical Applications: Python is the most suitable programming language for data science, artificial intelligence, and machine learning as it has numerous libraries to solve complex calculations easily and accurately. Some of the popular libraries used in developing numeric and scientific applications are Pandas, NumPy, Matplotlib, SciPy, and Scikit-learn.

Image Processing Applications: Python is used to manipulate images for digital image processing using libraries such as SimpleITK, OpenCV, and Pillow. 

Audio or Video-based Applications: Python is used to create multimedia applications along with speech recognition features through libraries like QT Python, Pyglet, and Gstreamer. 

Python Basics for Beginners 

Python Programming language is easy for beginners and our Python Training in Chennai provides a comprehensive understanding of python web development, data science process, and script development. Here we give some of the fundamental concepts of Python with examples.

Data Types: In-built data types of Python programming languages are

Data Types
Text Typestr
Example: x = “Hello World”
Numeric Typeint, float, complex
Examples: x = 10 //int
x = 10.5 //float
x = 1a //complex
Sequence Typelist, tuple, range
Examples: x = [“one”, “two”, “three”] //list
x = (“one”, “two”, “three”) //tuple
x = range(4) //range
Mapping Typedict
Example:x = {“Name” : “Shan”, “Age” : 34} //dict
Set Typeset, frozenset
Examples: x = {“one”, “two”, “three”} //set
x = frozenset({“one”, “two”, “three”}) //frozenset
Boolean Typeset, frozenset
Example x = true //bool
Binary Typebytes, bytearray, memroyview
Examples:x = bytearray(4) //bytearray
x = memoryview(bytes(5)) //memoryview


Operators in Python are used to perform operations of variables and values. Following are the operators used in Python.

  • Arithmetic Operators: Addition, Subtraction, Multiplication, Division, Modulus, Exponentiation, and Floor Division
  • Assignment Operators: =, +=, -+, *=, /=, %=, //=, **=, &=, |=, ^=, >>=, and <<=.
  • Comparison Operators: Equal, Not Equal, Greater than, Less than, Greater than or equal to, and Less than or equal to.
  • Logical Operators: And, Or, and Not.
  • Identity Operators: Is, and Is Not
  • Membership Operators: In, and Not In
  • Bitwise Operators: AND, OR, XOR, NOT, Zero fill the right shift, and Signed right shift.

OOPs concepts in Python Programming Language

Python is the object-oriented programming language that uses objects and classes in programming. The important thing of OOPs is to bind the data and the functions in a single unit for the easy accessibility of codes to other parts of the program. Following are the OOPs concepts in Python.

Class: A class is a collection of objects and contains a prototype from where the objects are being generated. 

The syntax for class definition in Python

              class ClassName:

                             #statement – 1


                             #statement -N

Objects: This is an entity and it consists of behavior, state, and identity. The state represents the attributes and it reflects the properties of an object. Behavior is representing the methods of an object and it reflects the response of an object to others. Identity gives a unique name to an object and allows one object to interact with others. 

Example for creating an object in Python

              obj = flower()

Inheritance: Inheritance is the concept that one class derives or inherits the properties of another class through objects. The class that inherits the properties is called the derived class or child class, while the class from which properties are derived is called the base class or parent class. There are single inheritance, multiple inheritances, multilevel inheritance, hierarchical inheritance, and hybrid inheritance in the Python programming language.

Polymorphism: Polymorphism means that one function or method takes multiple forms to provide various function types.

Encapsulation: It is the idea of wrapping the data and the methods that work on data within a single unit. A class is the best example of encapsulation in that it wraps all objects and functions in a class name.

Furthermore, there are ten major concepts that every beginner should know in Python programming languages. 

  • Map Function
  • Itertools
  • Lambda Function
  • Exception Handling
  • Decorators
  • Collections
  • Generators
  • Magic Methods
  • Threading
  • Regular Expressions
