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 20^th 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.
• Versatility: Python is a versatile language that supports multiple programming paradigms, including procedural, object-oriented, and functional programming. This flexibility makes it suitable for a wide range of applications, from web development to data science.
• Community and Libraries: Python boasts a vast and active community of developers. This community contributes to an extensive library of modules and packages, allowing you to leverage existing code for your projects. Whether you're into web development (Django, Flask), data analysis (Pandas, NumPy), or machine learning (TensorFlow, PyTorch), Python has you covered.
• Career Opportunities: Python is in high demand in the job market. Its popularity across various industries, including tech, finance, and data science, makes it a valuable skill to have on your resume.
