title: Check if item in list contains a number
body: <p>I've been trying to iterate over a list in order to find the first item which contains a number.
  I came across <code>any()</code> which doesn't seem to be able to 'search' for a number within an item of a list.</p>
  
  <p>If I take for instance the following list:</p>
  
  <pre><code>["Hello", "World(2)", "Bye 3"]
  </code></pre>
  
  <p>The first item in the list which contains a number is on position 1 [World(2)].</p>
  
  <p>Whether some of the following items after the first occurrence 'carry' a number is not relevant.</p>
  
  <p>I started with the following:</p>
  
  <pre><code>list1 = ["Hello", "World(2)", "Bye 3"]
  
  for x in list1:
       if x is.digit():        #this method doesn't work because it's only true when the whole item contains numbers.
         x = first_item_where_a_number_appears
  </code></pre>
  
  <p>It would be nice if someone could give a hint to the right approach.</p>
