Please explain what this code is

Question

a=[1, 2, 3]
print (“a”..”c”).zip(a)
#outputs [[“a”, 1], [“b”, 2], [“c”, 3]]
I dont understand what the .zip method does. Can someone please explain it?

Answer 1

.zip is useful for combining collections in an ordered way. We’ll first call it with two collections, one as the message receiver and one as the message’s argument:array.zip(other_array) The order is irrelevant for now. .zip will return arrays made by combining the collections piece by piece.

So far, simple:

[1,2,3].zip(['a', 'b', 'c']) #=> [[1, "a"], [2, "b"], [3, "c"]]

ex:-

a=[1,2,3]
print('a'.. 'c') =['a', 'b', 'c']
print('a'.. 'c').zip[1,2,3]=># will be written as below
print('a','b','c').zip[1,2,3]
it print the list element in order 0th element combine with 0th element of other list and so on
so 'a' is combine with 1 'b' is combine with 2 and 'c' is combine with 3 so output came as
[['a', 1],['b',2],['c', 3]]
