Im trying to convert to_sym.

So i know this is totally wrong but im stumped. Trying to iterate over a array and make them all symbols.

arr_num = [1,2,3,4]

arr_num.each_index do |ind|
        print ind.collect {|co| co.to_sym puts co}
        puts ind
        end

Hi Alphonse Cuccurullo,

Can you please format your code properly so people can debug you code?

If you do this:

name = "Alex"

There won't be any formating. If you do that for multiple lines, it is unreadable.

However, if you do this instead:

```ruby

name = "Alex"

```

it will look like this:

name = "Alex"

Please use formatting when posting code.

Thanks! ~Alex

If you just want an array of symbols made from this, you can write:

arr_num.map {|num| num.to_s.to_sym }

or a shorthand version:

arr.map(&:to_s.to_sym)

You can't convert numbers directly into symbols - you have to turn them into strings first.
