Introduction of python and get started to learn basic’s of python
Python is a powerful modern computer programming language. Python is the great language and most popular nowadays. Python today stands amongst the top 5 most popular and practical programming languages.
In technical terms, Python is an object-oriented, high-level programming language, object-oriented, interactive, interpreted and extremely user-friendly programming language.
By official introduction to Python is:
Python is an easy to learn, powerful programming language. It has efficient high-level data structures and a simple but effective approach to object-oriented programming. Python’s elegant syntax and dynamic typing, together with its interpreted nature, make it an ideal language for scripting and rapid application development in many areas on most platforms.
Python was developed by Guido van Rossum, and it is free software. Python is perhaps the only language that focuses on making things easier for the programmer to make more productive because it is very simple to use and write less code. Python is an interpreted language, which means that the written code is not actually translated to a computer-readable format at runtime. It will execute the code line by line.
Python was not so popular earlier even it used many places like web application, the mobile application as a scripting language. After coming to the Artifical Intelligence and Machine learning it popularity growth has increased so fast.
