1. Introduction to Python
Python was designed by Guido van Rossum of the Netherlands Research Society for Mathematics and Computer Science in the early 1990s as an alternative to a language called ABC. Python provides efficient high-level data structures and simple and effective object-oriented programming. Python syntax and dynamic types, as well as the nature of interpreted languages, make it a programming language for writing scripts and rapidly developing applications on most platforms. Development of large projects.
