    en.wikipedia.org/wiki/Python_syntax_and_semantics

    Numeric literals in Python are of the normal sort, e.g. 0, -1, 3.4, 3.5e-8. Python has arbitrary-length integers and automatically increases their storage size as necessary. Prior to Python 3, there were two kinds of integral numbers: traditional fixed size integers and "long" integers of arbitrary size.

  5. Syntax (programming languages) - Wikipedia

    en.wikipedia.org/wiki/Syntax_(programming_languages)

    The phrase grammar of most programming languages can be specified using a Type-2 grammar, i.e., they are context-free grammars, [8] though the overall syntax is context-sensitive (due to variable declarations and nested scopes), hence Type-1. However, there are exceptions, and for some languages the phrase grammar is Type-0 (Turing-complete).

  6. List comprehension - Wikipedia

    en.wikipedia.org/wiki/List_comprehension

    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.

  7. Semicolon - Wikipedia

    en.wikipedia.org/wiki/Semicolon

    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.

  8. Comma code - Wikipedia

    en.wikipedia.org/wiki/Comma_code

    Of course we use a single comma to separate each field of data, therefore showing that all the data consists of 50% of commas. This is quite visible from an implied probability of 50% for the 0 code in Huffman base 3 codes: 0,10,11 (net 2/3 or 66.66% commas) or the base-5 comma code shown

  9. Definite clause grammar - Wikipedia

    en.wikipedia.org/wiki/Definite_clause_grammar

    A definite clause grammar (DCG) is a way of expressing grammar, either for natural or formal languages, in a logic programming language such as Prolog. It is closely related to the concept of attribute grammars / affix grammars .
