A whitespace character is a character data element that represents white space when text is rendered for display by a computer. For example, a space character (U+0020 SPACE, ASCII 32) represents blank space such as a word divider in a Western script. A printable character results in output when rendered, but a whitespace character does not.
Whitespace is an esoteric programming language with syntax where only whitespace characters (space, tab and linefeed) have meaning – contrasting typical languages that largely ignore whitespace characters. [1][2] As a consequence of its syntax, Whitespace source code can be contained within the whitespace of code written in a language that ...
Space (punctuation) In writing, a space ( ) is a blank area that separates words, sentences, syllables (in syllabification) and other written or printed glyphs (characters). Conventions for spacing vary among languages, and in some languages the spacing rules are complex. [citation needed] Inter-word spaces ease the reader's task of identifying ...
In word processing and digital typesetting, a non-breaking space ( ), also called NBSP, required space, [1] hard space, or fixed space (in most typefaces, it is not of fixed width), is a space character that prevents an automatic line break at its position. In some formats, including HTML, it also prevents consecutive whitespace characters from ...
Coding conventions are a set of guidelines for a specific programming language that recommend programming style, practices, and methods for each aspect of a program written in that language. These conventions usually cover file organization, indentation, comments, declarations, statements, white space, naming conventions, programming practices ...
A free-format language ignores whitespace characters: spaces, tabs and new lines so the programmer is free to style the code in different ways without affecting the meaning of the code. Generally, the programmer uses style that is considered to enhance readability. The two code snippets below are the same logically, but differ in whitespace.
Syntax definition. Parse tree of Python code with inset tokenization. The syntax of textual programming languages is usually defined using a combination of regular expressions (for lexical structure) and Backus–Naur form (a metalanguage for grammatical structure) to inductively specify syntactic categories (nonterminal) and terminal symbols.

String literal. A string literal or anonymous string is a literal for a string value in the source code of a computer program. Modern programming languages commonly use a quoted sequence of characters, formally "bracketed delimiters", as in x = "foo", where , "foo" is a string literal with value foo. Methods such as escape sequences can be used ...
