使用Ruby，我如何迭代for循环n次

I have a basic ruby loop

I want to run this loop 2 or 3 times.

我想运行这个循环2或3次。

Is this possible?

这可能吗？

2 个解决方案

3.times do
   # do work here
end

查看http://www.tutorialspoint.com/ruby/ruby_loops.htm

It's bad style to use for.

这是糟糕的风格。

3.times do
  site.posts.each do |video|
    video.some_parameter
  end
end

or if video.some_parameter is one line,

或者如果video.some_parameter是一行，

3.times do
  site.posts.each { |video| video.some_parameter }
end
