list = %w( a b c ) # there's a for statement but nobody likes it :P for item in list puts item end # so you use the each method with a block instead # one-liner block list.each { |item| puts item } # multi-line block list.each do |item| puts item end Comments
foo = [3, 6, 3] foo.each do |a| puts a end

foo = [1, 2, 3] foo.each do |x| puts x end

Your already have both correct answers about "for"-loop. But in Exactly your example, i'll use:
puts foo Also you can use this puts' feature in such case:
puts array.map { |i| ...some code...; x } instead of
array.each { |i| ...some code...; puts x } for example, if you want to call puts only once.
