What is python ?

Python is a very simple programming language, developed by Guido van Rossum in 1989. It is

named after the comedy television show Monty Python‘s Flying Circus and not after the Python

snake. It is easy to learn to all who are new to programming.

Python is a dynamic, interpreted language. It is platform independent, free and open source, easy to learn, achieve the more tasks through less coding, fast in execution.

There are no type declarations of variables, parameters, functions, or methods in source code.

This makes the code short and flexible.

Python is a general-purpose language, which can be used in various domains including: Web

applications, Big data applications, Data science, Desktop software, Mobile apps, Machine

learning and AI. The SQL can be used for querying data from relational databases.

In our daily life we may require different tools to perform different tasks such as scissor for

cutting paper, screw driver for tightening of screw, removing the hook, scaling the fish or making

use of the scissors. If you can get one tool to perform plenty of task then that will be the most

preferred tool. Swiss knife is such a multi-functional tool having various tools such as blade,

opener, screwdriver, reamer and others one in all. In the same way Python is such a programming

language which is object oriented, functional programming and also declarative programming

language.

Python is a high-level programming language that makes it easy to learn. It doesn‘t require to

understand the details of the computer to develop programs efficiently. It is the robust

programming language used in many domains from web applications, data analysis, data science,

machine learning, and AI. It is important to understand the syntax and semantics to learn any

programming language.

What are the Features of Python programming ?

Python is an interpreted, high-level, general-purpose programming language. It allows solving

complex problems in less time and fewer lines of code. It is simple and easy-to-learn. Python can

be used to build all types of applications ranging from small and simple scripts to complex

machine learning algorithms. Python source code is available under the GNU General Public

License (GPL). The latest Python 3 release is Python 3.11.0. comes with the following features:

 Readable and Easy to Learn – Python is a very readable language. Python programs are

easy to understand as they have a clearly defined syntax and relatively simple structure. It

is an interpreted language, as Python programs are executed by an interpreter.

 Case Sensitive – Python is case-sensitive language in Python. Python uses indentation for blocks and nested blocks.

 Free and Open Source – Python is a free and open source programming language. This

means you can download it for free and use it in your application.

 Cross platform – Python is portable and platform independent. It can run on various

operating systems such as Mac, Windows, Linux, Unix and any hardware platforms. This

makes it a cross platform and portable language.

 Large standard library – Python comes with a large standard library of predefined

functions that has some handy codes and functions which can be used while writing code

in Python. Python is also helpful in web development. Many popular web services and

applications are built using Python.

 Supports exception handling – Python supports exception handling which means we can

write less error prone code and can test various scenarios that can cause an exception

later on.

 Advanced features – Supports generators and list comprehensions. We will cover these

features later.

 Automatic memory management – Python supports automatic memory management

which means the memory is cleared and freed automatically.

Some of the main uses of Python are:

 Used alongside software to create workflows.

 Used on a server to create web applications.

 Rapid prototyping or production-ready to use software development.

 Handle big data and perform complex mathematical calculations.

 Connect to database systems, read and modify files.

Python also has a rich set of libraries that makes it popular among software developers. It has

been widely used in development of software applications for various domains. In addition, Python

has simple easy-to-use syntax. This makes Python an excellent language to learn to program for

beginners also. Let us start working with Python Interpreter.
