Pygame is a cross-platform set of Python modules designed for writing video games. It includes computer graphics and sound libraries designed to be used with the Python programming language . [ 7 ]
Duck typing is similar to, but distinct from, structural typing.Structural typing is a static typing system that determines type compatibility and equivalence by a type's structure, whereas duck typing is dynamic and determines type compatibility by only that part of a type's structure that is accessed during runtime.
Esri promotes Python as the best choice for writing scripts in ArcGIS. [226] It has also been used in several video games, [227] [228] and has been adopted as first of the three available programming languages in Google App Engine, the other two being Java and Go. [229] Many operating systems include Python as a standard component.
In computer programming, lazy initialization is the tactic of delaying the creation of an object, the calculation of a value, or some other expensive process until the first time it is needed.

Löve (stylized in all caps) is a free, open-source, cross-platform framework released under the zlib license for developing video games.The framework is written in C++ and uses Lua as its scripting language and is still maintained by its original developers.
A strict programming language is a programming language that only allows strict functions (functions whose parameters must be evaluated completely before they may be called) to be defined by the user. A non-strict programming language allows the user to define non-strict functions, and hence may allow lazy evaluation.
In Python 3.x the range() function [28] returns a generator which computes elements of the list on demand. Elements are only generated when they are needed (e.g., when print(r[3]) is evaluated in the following example), so this is an example of lazy or deferred evaluation: >>>
