What is Python?

Python is a high-level, general-purpose programming language that was created by Guido van Rossum in 1991. It is an interpreted language, which means that the code is executed line by line, rather than being compiled into machine code before execution. Python has a simple & easy-to-learn syntax that emphasizes readability, making it a great language for beginners to learn.

Python is also an object-oriented language, which means that it uses objects & classes to organize code. This makes it easy to write reusable & modular code, which can be used across multiple projects. Python also has a large standard library that provides many useful functions & modules, such as string operations, file I/O, & web services.

One of the key features of Python is its dynamic typing, which means that variables can change type during runtime. This makes it easy to write flexible code that can adapt to different situations. Python also has automatic memory management, which means that the programmer does not need to worry about allocating & freeing memory manually.
