What is zip (functional programming?)

Question

I recently saw some Clojure or Scala (sorry I\'m not familiar with them) and they did zip on a list or something like that. What is zip and where did it come from ?

Answer 1

You could use the following code in Python:

>>> a = [1,2]
>>> b = [3,4]
>>> zip(a,b)
[(1,3),(2,4)]
