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:
“Talking about dreams is like talking about movies, since the cinema uses the language of dreams; years can pass in a second and you can hop from one place to another. It’s a language made of image. And in the real cinema, every object and every light means something, as in a dream.”
—Frederico Fellini (1920–1993)
“Envy and jealousy are the private parts of the human soul. Perhaps the comparison can be extended.”
—Friedrich Nietzsche (1844–1900)
