What is Python?
- Python is a general purpose high-level, interpreted programming language known for its simplicity and readability.
- Created by Guido van Rossum at National Institute in Netherland in 1989, Python has evolved into a powerful and widely-used language.
- Its design philosophy emphasizes code readability, and its syntax allows programmers to express concepts in fewer lines of code than languages like C++ or Java.
- It is publically available from 20th February 1991
- The word “python” is taken from a very popular TV show “Monty Python's Flying Circus” of 1967 - 74 broadcasted by BBC.
Why to choose/learn python?
- Ease of Learning: Python's syntax is straightforward and easy to grasp. If you're new to coding, Python is an excellent starting point. The emphasis on readability means you can write and understand Python code more quickly than in many other languages.
