1. History of Python Development

Python was created by Guido van Rossum and was first released in 1991. Its design philosophy emphasizes code readability, and its syntax allows programmers to express concepts in fewer lines of code compared to other languages like C++ or Java. Significant milestones in Python’s development include:

• Python 1.x (1991-2000): The initial release introduced core concepts like dynamic typing, exception handling, and module support.
• Python 2.x (2000-2020): A major update, featuring Unicode support, list comprehensions, and improvements to object-oriented programming. However, the 2.x series was discontinued in 2020.
• Python 3.x (2008-present): The transition to Python 3 introduced significant changes that broke backward compatibility with Python 2, emphasizing cleaner code, improved consistency, and optimizations.

Python’s growth surged with its adoption in various domains like web development, data science, machine learning, and scripting due to its simplicity, community-driven development, and rich ecosystem.
