Questions tagged [spaces]

The space character, `U+0020`, used to separate words/tokens in most natural and programming languages.

The space character, U+0020, used to separate words/tokens in most natural and programming languages. Space is a whitespace character.

Spaces are frequently of concern to programmers in the context of languages with significant whitespace (e.g. Python), source code indentation, and separating tokens. Separating tokens correctly is important for shell scripts, URIs, file names/paths, text processing, and string formatting. Questions regarding all of these areas are common on Stack Overflow, as spaces appearing unexpectedly can cause unexpected behavior whose source is not immediately obvious.

"Spaces" may also refer to the virtual desktop functionality of Mac OS X, first referred to as "Spaces" in OS X 10.5.
