what is Python?

Guido van Rossum created Python, an interpreted, object-oriented, high-level computer language with dynamic semantics. It was first made available in 1991. The name "Python" is a tribute to a British comedy group Monty Python and is meant to both be simple and entertaining. The syntax of Python is straightforward and resembles that of English. Python's syntax differs from various other computer languages in that it enables programmers to construct applications with fewer code lines. Python operates over an interpreter system, allowing for immediate execution of written code. As a result, prototyping can proceed quickly. Python is a dynamic, bytecode-compiled, and programming language. Variable, parameter, method, and method types are not declared in the source code.
