title: How to check if a list contains a string
body: <p>I need to iterate through a list and check if the value is a string or an int. Is there any easy way to do this in python?</p>
  
  <p>For example:</p>
  
  <p><code>[1,2,3]</code> would be true.</p>
  
  <p><code>["a",2,3]</code> would be false.</p>
