title: How to check if string include symbols?
body: <p>How can I check if a string include symbol? It looks confusing to me: </p>
  
  <pre><code>class Beba 
    def initialize
      while true
        puts "Qfar emri deshironi ti vnoni bebes?"
        @@emri = gets.chomp.capitalize
  
        if @@emri.scan(/\d+/).empty? &amp;&amp; @@emri.scan(/\/./).empty?
          puts "Ti e emertove beben me emrin: #{@@emri}"
          break 
        else
          puts "Emri nuk mund te jete me numra/simbole, provoni perseri."
        end
      end
    end 
  end
  </code></pre>
  
  <p>As you can see, at <code>if@@emri.scan(/\d+/).empty? &amp;&amp; @@emri.scan(/\/./).empty?</code>, I don't know what to do, like which method can I use for <code>@@emri.scan(/\\.\).empty?</code> to check if my string doesn't include any symbol?</p>
