The core of extensible programming is defining functions. Python allows mandatory and optional arguments, keyword arguments, and even arbitrary argument lists. More about defining functions in Python 3 Lists (known as arrays in other languages) are one of the compound data types that Python understands.

Lists can be indexed, sliced and manipulated with other built-in functions. More about lists in Python 3 Calculations are simple with Python, and expression syntax is straightforward: the operators +, -, * and / work as expected; parentheses () can be used for grouping. More about simple math functions in Python 3. Python knows the usual control flow statements that other languages speak — if, for, while and range — with some of its own twists, of course.

Its design philosophy emphasizes code readability with the use of significant indentation.[34] Python is dynamically type-checked and garbage-collected. It supports multiple programming paradigms, including structured (particularly procedural), object-oriented and functional programming. Guido van Rossum began working on Python in the late 1980s as a successor to the ABC programming language. Python 3.0, released in 2008, was a major revision and not completely backward-compatible with earlier versions. Beginning with Python 3.5,[35] capabilities and keywords for typing were added to the language, allowing optional static typing.[36] Currently only versions in the 3.x series are supported. Python has gained widespread use in the machine learning community.[37][38][39][40] It is widely taught as an introductory programming language.[41] Since 2003, Python has consistently ranked in the top ten of the most popular programming...

Python was conceived in the late 1980s[43] by Guido van Rossum at Centrum Wiskunde & Informatica (CWI) in the Netherlands.[44] It was designed as a successor to the ABC programming language, which was inspired... The name Python derives from the British comedy series Monty Python's Flying Circus.[49] (See § Naming.) Created with over a decade of experience.
