enumerate

enumerate(iter)

An iterator that yields (i, x) where i is an index starting at 1, and x is the ith value from the given iterator. It's useful when you need not only the values x over which you are iterating, but also the index i of the iterations.

julia> a = ["a", "b", "c"];

julia> for (index, value) in enumerate(a)
           println("$index $value")
       end
1 a
2 b
3 c

Examples

julia> a = ["a", "b", "c"];
       for (index, value) in enumerate(a)
           println("$index $value")
       end
1 a
2 b
3 c

julia> foo = [-1, -2, -3];
julia> for (index, value) in enumerate(foo)
            println("Element at index $index : $value")
        end
Element at index 1 : -1
Element at index 2 : -2
Element at index 3 : -3
