The term closure is often used as a synonym for anonymous function, though strictly, an anonymous function is a function literal without a name, while a closure is an instance of a function, a value, whose non-local variables have been bound either to values or to storage locations (depending on the language; see the lexical environment section below).
Python has had support for lexical closures since version 2.2. Here's an example function that returns a function that approximates the derivative of the given function: def derivative ( f , dx ): """Return a function that approximates the derivative of f using an interval of dx, which should be appropriately small. """ def function ( x ...
The main property of closed sets, which results immediately from the definition, is that every intersection of closed sets is a closed set. It follows that for every subset Y of S , there is a smallest closed subset X of S such that Y ⊆ X {\displaystyle Y\subseteq X} (it is the intersection of all closed subsets that contain Y ).
In computer programming, an anonymous function (function literal, expression or block) is a function definition that is not bound to an identifier.Anonymous functions are often arguments being passed to higher-order functions or used for constructing the result of a higher-order function that needs to return a function.

Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. [33] Python is dynamically type-checked and garbage-collected. It supports multiple programming paradigms, including structured (particularly procedural), object-oriented and functional ...

The closure could affect jobs for more than 150,000 people who work in and around the port, and could cost the economy as a whole about $15 million per day. Delays may have a particular effect on ...
In mathematical logic and computer science, the Kleene star (or Kleene operator or Kleene closure) is a unary operation, either on sets of strings or on sets of symbols or characters. In mathematics, it is more commonly known as the free monoid construction.
