Introduction to Python:
Python was developed by Guido van Rossum and was released first on February 20, 1991. It is one of the most widely-used and loved programming languages and is interpreted in nature thereby providing flexibility of incorporating dynamic semantics. It is also a free and open-source language with very simple and clean syntax. This makes it easy for developers to learn python. Python also supports object-oriented programming and is most commonly used to perform general-purpose programming.
Due to its simplistic nature and the ability to achieve multiple functionalities in fewer lines of code, python’s popularity is growing tremendously. Python is also used in Machine Learning, Artificial Intelligence, Web Development, Web Scraping, and various other domains due to its ability to support powerful computations using powerful libraries. Due to this, there is a huge demand for python developers in India and across the world. Companies are willing to offer amazing perks and benefits to these developers.

Python Interview Questions for Freshers
In this article, we will look at some of the most commonly asked Python interview questions with answers which will help you prepare for your upcoming job interviews.
1. What is Python? What are the benefits of using Python
Python is a high-level, interpreted, general-purpose programming language. Being a general-purpose language, it can be used to build almost any type of application with the right tools/libraries. Additionally, python supports objects, modules, threads, exception-handling, and automatic memory management which help in modelling real-world problems and building applications to solve these problems.
Benefits of using Python:
- Its high-level data structures, combined with dynamic typing and dynamic binding, attract a huge community of developers for Rapid Application Development and deployment.
- Python is a general-purpose programming language that has a simple, easy-to-learn syntax that emphasizes readability and therefore reduces the cost of program maintenance. Moreover, the language is capable of scripting, is completely open-source, and supports third-party packages encouraging modularity and code reuse.
2) Why Python?
- Python is an interpreted, object-oriented, high-level programming language with dynamic semantics.
- Python is compatible with different platforms like Windows, Mac, Linux, Raspberry Pi, etc.
- Python has a simple syntax as compared to other languages.
- Python allows a developer to write programs with fewer lines than some other programming languages.
- Python runs on an interpreter system, means that the code can be executed as soon as it is written. It helps to provide a prototype very quickly.
- Python can be described as a procedural way, an object-orientated way or a functional way.
- The Python interpreter and the extensive standard library are available in source or binary form without charge for all major platforms, and can be freely distributed.
4) What are the advantages of Python?
Advantages of Python are:
- Python is Interpreted language
Interpreted: Python is an interpreted language. It does not require prior compilation of code and executes instructions directly.
- It is Free and open source
Free and open source: It is an open-source project which is publicly available to reuse. It can be downloaded free of cost.
- It is Extensible
Extensible: It is very flexible and extensible with any module.
- Object-oriented
Object-oriented: Python allows to implement the Object-Oriented concepts to build application solution.
- It has Built-in data structure
Built-in data structure: Tuple, List, and Dictionary are useful integrated data structures provided by the language.
- Readability
- High-Level Language
- Cross-platform
Portable: Python programs can run on cross platforms without affecting its performance.
3) What are the applications of Python?
Python is used in various software domains some application areas are given below.
- Web and Internet Development
- Games
- Scientific and computational applications
- Language development
- Image processing and graphic design applications
- Enterprise and business applications development
