Questions tagged [take]

Take is a common keyword or function name used to return a given number of elements, usually contiguously and from the beginning of a collection. Only use this tag for the take keyword or function name; usage such as "take a picture/screenshot" is out of scope.

Take functions usually only require two pieces of information: the number of elements to be returned from the sequence, and the sequence itself.

If take is a method in a particular library or language, it is called on the object and would only require the number parameter.

This concept is found in many languages and libraries, some of which are listed below.
