Accessing the count/iteration # within an "each"?

Ruby

Hi,

Is there a way to access the count / iteration# within an “each” loop?
i.e.
how many times through the loop one is?

testhash.each { |d|
puts

}

Tks

how many times through the loop one is?

testhash.each { |d|
puts

}

testhash.each_with_index {|d, i| puts i}

ruby$ ri Enumerable#each_with_index
--------------------------------------------- Enumerable#each_with_index
enum.each_with_index {|obj, i| block } -> enum

 Calls block with two arguments, the item and its index, for each
 item in enum.

    hash = Hash.new
    %w(cat dog wombat).each_with_index {|item, index|
      hash[item] = index
    }
    hash   #=> {"cat"=>0, "wombat"=>2, "dog"=>1}
