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 ...
Python The use of the triple-quotes to comment-out lines of source, does not actually form a comment. [ 21 ] 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 ).
A stylistic depiction of values inside of a so-named comma-separated values (CSV) text file. The commas (shown in red) are used as field delimiters. A delimiter is a sequence of one or more characters for specifying the boundary between separate, independent regions in plain text, mathematical expressions or other data streams.
Here, the list [0..] represents , x^2>3 represents the predicate, and 2*x represents the output expression.. List comprehensions give results in a defined order (unlike the members of sets); and list comprehensions may generate the members of a list in order, rather than produce the entirety of the list thus allowing, for example, the previous Haskell definition of the members of an infinite list.
[3] [4] [5] For example, a list of three countries might be punctuated without the serial comma as "France, Italy and Spain" or with the serial comma as "France, Italy, and Spain". The serial comma can help avoid ambiguity in some situations, but can also create it in others. [6] There is no universally accepted standard for when to use the ...

In Microsoft Excel, the semicolon is used as a list separator, especially in cases where the decimal separator is a comma, such as 0,32; 3,14; 4,50, instead of 0.32, 3.14, 4.50. In Lua, [51] semicolons or commas can be used to separate table elements.
