Question

Otherwise, it needs to be

h = {:a => 1, :b => 2.2}
h.each_with_index do |pair, i|
  k = pair[0]; v = pair[1]
  p k, v, i
end

and setting the k and v this way seems a bit clumsy. Can it be simpler or something like

h.each_with_index do |[k,v], i|

?

Answer 1

In fact, yes! Use parentheses:

h = {:a => 1, :b => 2.2}
h.each_with_index do |(k, v), i|
  p k, v, i
end
