Language Comparison
List of languages by support of convolution:
| Language | Zip | Zip 3 lists | Zip n lists | Notes |
|---|---|---|---|---|
| Clojure | (map list list1 list2) (map vector list1 list2) |
(map vector list1 list2 list3) (map vector list1 list2 list3) |
(map list list1 … listn) (map vector list1 … listn) |
Stops after the length of the shortest list. |
| Common Lisp | (mapcar #'list list1 list2) | (mapcar #'list list1 list2 list3) | (mapcar #'list list1 ... listn) | Stops after the length of the shortest list. |
| Haskell | zip list1 list2 | zip3 list1 list2 list3 | zipn list1 … listn | zipn for n > 3 is available in the module Data.List. Stops after the shortest list ends. |
| Python | zip(list1, list2) | zip(list1, list2, list3) | zip(list1, …, listn) | zip and map (3.x) stops after the shortest list ends, whereas map (2.x) and itertools.zip_longest (3.x) extends the shorter lists with None items |
| Language | Unzip | Unzip 3 tuples | Unzip n tuples | Notes |
|---|---|---|---|---|
| Clojure | (apply map vector convlist) | (apply map vector convlist) | (apply map vector convlist) | |
| Common Lisp | (apply #'mapcar #'list convlist) | (apply #'mapcar #'list convlist) | (apply #'mapcar #'list convlist) | |
| Haskell | unzip convlist | unzip3 convlist | unzipn convlist | unzipn for n > 3 is available in the module Data.List. |
| Python | zip(*convvlist) | zip(*convvlist) | zip(*convvlist) |

Famous quotes containing the words language and/or comparison:
“Strange goings on! Jones did it slowly, deliberately, in the bathroom, with a knife, at midnight. What he did was butter a piece of toast. We are too familiar with the language of action to notice at first an anomaly: the ‘it’ of ‘Jones did it slowly, deliberately,...’ seems to refer to some entity, presumably an action, that is then characterized in a number of ways.”
—Donald Davidson (b. 1917)
“Clay answered the petition by declaring that while he looked on the institution of slavery as an evil, it was ‘nothing in comparison with the far greater evil which would inevitably flow from a sudden and indiscriminate emancipation.’”
—State of Indiana, U.S. public relief program (1935-1943)
