Automatic counter in Ruby for each?

Question

I want to use a for-each and a counter:

i=0
for blah in blahs
    puts i.to_s + \" \" + blah
    i+=1
end

Is there a better way to do it?

Answer 1

If you want to get index of ruby for each, then you can use

.each_with_index

Here is an example to show how .each_with_index works:

range = ('a'..'z').to_a
length = range.length - 1
range.each_with_index do |letter, index|
    print letter + " "
    if index == length
        puts "You are at last item"
    end
end

This will print:

a b c d e f g h i j k l m n o p q r s t u v w x y z You are at last item
