The serial comma (also referred to as the series comma, Oxford comma, [1] or Harvard comma [2]) is a comma placed after the second-to-last term in a list (just before the conjunction) when writing out three or more terms.
The enclosed text becomes a string literal, which Python usually ignores (except when it is the first statement in the body of a module, class or function; see docstring). Elixir. The above trick used in Python also works in Elixir, but the compiler will throw a warning if it spots this.
The comma operator separates expressions (which have value) in a way analogous to how the semicolon terminates statements, and sequences of expressions are enclosed in parentheses analogously to how sequences of statements are enclosed in braces: [1] (a, b, c) is a sequence of expressions, separated by commas, which evaluates to the last expression c, while {a; b; c;} is a sequence of ...
In addition, Python also has 3 soft keywords. Unlike regular hard keywords, soft keywords are reserved words only in the limited contexts where interpreting them as keywords would make syntactic sense. These words can be used as identifiers elsewhere, in other words, match and case are valid names for functions and variables. [6] [7] _ [note 4 ...
In file systems, the dot is commonly used to separate the extension of a file name from the name of the file (e.g., filename.mp4). RISC OS uses dots to separate levels of the hierarchical file system when writing path names—similar to / (forward-slash) in Unix -based systems and \ (back-slash) in MS-DOS -based systems and the Windows NT ...
Because the comma after "mother" is conventionally used to prepare the reader for an appositive phrase – that is, a renaming of or further information about a noun – this construction formally suggests that my mother's name is "Anne Smith and Thomas". Because that is implausible, it is relatively clear that the construction refers to two ...
Symbol-specific names are also used; decimal point and decimal comma refer to a dot (either baseline or middle) and comma respectively, when it is used as a decimal separator; these are the usual terms used in English, [1] [2] [3] with the aforementioned generic terms reserved for abstract usage.
Comma-separated values is a data format that predates personal computers by more than a decade: the IBM Fortran (level H extended) compiler under OS/360 supported CSV in 1972. [14] List-directed ("free form") input/output was defined in FORTRAN 77, approved in 1978. List-directed input used commas or spaces for delimiters, so unquoted character ...
