Python Zero To Hero.
What is Python?
Python is a high-level, interpreted programming language known for its readability and simplicity. It's widely used for web development, data analysis, AI, and more. Key features include dynamic typing, a large standard library, cross-platform compatibility, an active community, and support for object-oriented programming. Python's unique feature is its use of indentation for defining code blocks and enhancing readability. It's a versatile and popular language in computer science and other domains.
History of Python.
The history of Python is a fascinating journey that began in the late 1980s and has since evolved into one of the most popular and versatile programming languages. Here's a brief overview of Python's history:
Birth of Python (Late 1980s): Python was created by Guido van Rossum, a Dutch programmer, in the late 1980s. Guido started working on Python in December 1989 and released its first version, Python 0.9.0, in February 1991. He aimed to develop a language that was easy to read, write, and maintain, inspired by the ABC language he had worked on at Centrum Wiskunde & Informatica (CWI) in the Netherlands.
Python 1.0 (January 1994): Python 1.0 was released with several new features, including lambda, map, filter, and reduce functions. This release marked Python's transition from an internal project to a publicly available programming language.
Python 2.0 (October 2000): Python 2.0 introduced list comprehensions, garbage collection, and Unicode support. This version of Python gained significant popularity and remained the dominant version for many years.
Python 3.0 (December 2008): Python 3.0, also known as Python 3000 or Py3k, was a major milestone. It introduced several backward-incompatible changes to address inconsistencies and improve the language's design. Key changes included a new print function, improved Unicode handling, and the removal of legacy features.
Python's Growth and Popularity: Python's simplicity, readability, and versatility contributed to its rapid adoption in various domains, including web development (Django, Flask), scientific computing (NumPy, SciPy), data analysis (Pandas), and artificial intelligence and machine learning (TensorFlow, PyTorch).
Python Software Foundation (PSF): In 2001, the Python community established the Python Software Foundation (PSF), a non-profit organization dedicated to the development and promotion of Python. The PSF helps fund Python development, conferences, and community initiatives.
Continued Evolution: Python continues to evolve, with regular releases introducing new features and improvements. Python 2 reached its end of life on January 1, 2020, and Python 3 is now the primary focus of development.
Python's Influence: Python's design principles and readability have influenced the development of other programming languages. Its design philosophy is encapsulated in the "Zen of Python" (PEP 20), a collection of guiding aphorisms for writing computer programs.
And the python continues his journey of evolution till today.
