Ruby - every nth iteration

Question

How to print "Hello" every nth iteration in ruby, using something like:

50.times do # every nth say hello end 

Answer 1

I don't think times will work in this case. But instead, you can iterate over the range:

 (1..50).each do |i| # print hello if number of iteration is multiple of five puts 'Hello' if i % 5 == 0 # do other stuff end 

Updated (thanks to d11wtq)

It turned out that Integer#times also gives the iteration number to the block:

 50.times do |i| # print hello if number of iteration is multiple of five puts 'Hello' if (i + 1) % 5 == 0 # do other stuff end 

The numbering is zero, so we add 1 to the iteration number (you can use i % 5 == 4 instead, but that looks less obvious).

Answer 2

 (0..10).step(2) do |it| puts it end 

Outputs:

 0 2 4 6 8 10
