Set-builder notation can be used to describe a set that is defined by a predicate, that is, a logical formula that evaluates to true for an element of the set, and false otherwise. [2] In this form, set-builder notation has three parts: a variable, a colon or vertical bar separator, and a predicate. Thus there is a variable on the left of the ...
Semantic definitions and definitions using set-builder notation are examples. An extensional definition describes a set by listing all its elements. [19] Such definitions are also called enumerative. An ostensive definition is one that describes a set by giving examples of elements; a roster involving an ellipsis would be an example.
It follows the form of the mathematical set-builder notation (set comprehension) as distinct from the use of map and filter functions. Examples of list comprehension [ edit ]
An important special case is when the index set is , the natural numbers: this Cartesian product is the set of all infinite sequences with the i-th term in its corresponding set X i. For example, each element of ∏ n = 1 ∞ R = R × R × ⋯ {\displaystyle \prod _{n=1}^{\infty }\mathbb {R} =\mathbb {R} \times \mathbb {R} \times \cdots } can ...
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.
CLEVELAND — The Detroit Tigers have finalized their 26-man MLB playoff roster for the ALDS matchup against the Cleveland Guardians, setting the stage for Game 1 on Saturday (TBS, TruTV).
This notation is called set-builder notation (or "set comprehension", particularly in the context of Functional programming). Some variants of set builder notation are: {x ∈ A | P(x)} denotes the set of all x that are already members of A such that the condition P holds for x.
