In type theory, a typing rule is an inference rule that describes how a type system assigns a type to a syntactic construction. [ 1 ] : 94 These rules may be applied by the type system to determine if a program is well-typed and what type expressions have.
The data type should preferably be immutable if possible. It is common for implementations to handle equality testing, serialization and model binding. The strongly typed identifier commonly wraps the data type used as the primary key in the database, such as a string, an integer or universally unique identifier (UUID).
For example, if we write (,) for n-tuples of real numbers, then : (,) would be the type of a function which, given a natural number n, returns a tuple of real numbers of size n. The usual function space arises as a special case when the range type does not actually depend on the input.
The standard type hierarchy of Python 3. In computer science and computer programming, a data type (or simply type) is a collection or grouping of data values, usually specified by a set of possible values, a set of allowed operations on these values, and/or a representation of these values as machine types.

This is a list of file formats used by computers, organized by type. Filename extension is usually noted in parentheses if they differ from the file format 's name or abbreviation. Many operating systems do not limit filenames to one extension shorter than 4 characters, as was common with some operating systems that supported the File ...
The Linda model provides a distributed shared memory, known as a tuple space because its basic addressable unit is a tuple, an ordered sequence of typed data objects; specifically in Linda, a tuple is a sequence of up to 16 typed fields enclosed in parentheses". The tuple space is "logically shared by processes" which are referred to as workers ...
