List comprehension. A list comprehension is a syntactic construct available in some programming languages for creating a list based on existing lists. It follows the form of the mathematical set-builder notation ( set comprehension) as distinct from the use of map and filter functions.

It follows the form of the mathematical set-builder notation ( set comprehension) as distinct from the use of map and filter functions.
The various object-oriented programming languages enforce member accessibility and visibility to various degrees, and depending on the language's type system and compilation policies, enforced at either compile time or runtime. For example, the Java language does not allow client code that accesses the private data of a class to compile. [12]
Objects are instances of a class. Object-oriented programming ( OOP) is a programming paradigm based on the concept of objects, [ 1] which can contain data and code: data in the form of fields (often known as attributes or properties ), and code in the form of procedures (often known as methods ).
A "Hello, World!" program is generally a simple computer program which emits (or displays) to the screen (often the console) a message similar to "Hello, World!" while ignoring any user input. A small piece of code in most general-purpose programming languages, this program is used to illustrate a language's basic syntax.

Karel, Karel++, and Karel J. Robot are languages aimed at beginners, used to control a simple robot in a city consisting of a rectangular grid of streets. While Karel is its own language, Karel++ is a version of Karel implemented in C++, while Karel J. Robot is a version of Karel implemented in Java.
For example, C++ is a multi-paradigm language including object-oriented paradigm; [2] however, it is less object-oriented than some other languages such as Python [3] and Ruby. [4] Therefore, some people consider C++ an OOP language, while others do not or refer to it as a "semi-object-oriented programming language".
