Python is a high-level, interpreted programming language that is widely used for web development, artificial intelligence, data analysis, and scientific computing. It is known for its simplicity, readability, and flexibility; as well as, its large and active developer community.
Python is an object-oriented language. It's based on the concept of "objects", which are data structures that contain data and functionality. Python also supports procedural and functional programming styles.
One of the main benefits of Python is its large standard library, which provides many useful modules and functions for a wide range of tasks, including connecting to web servers, reading and writing files, and working with data. Python also has a large ecosystem of third-party libraries and frameworks, making it a good choice for many types of projects.
