Python is a popular, general purpose, high-level programming language that is easy to interface with other languages. It has a clear, readable syntax and large standard library. It can be used for a wide range of applications including web development, desktop GUIs, games, science, and more. Major organizations like Google, Yahoo, NASA, and CERN use Python for applications like YouTube, Gmail, mapping tools, and scientific calculations due to its simplicity and flexibility.
