title: How to detect lowercase letters in Python?
body: <p>I need to know if there is a function that detects the lowercase letters in a string. Say I started writing this program:</p>
  <pre><code>s = input('Type a word')
  </code></pre>
  <p>Would there be a function that lets me detect a lowercase letter within the string s? Possibly ending up with assigning those letters to a different variable, or just printing the lowercase letters or number of lowercase letters.</p>
  <p>While those would be what I would like to do with it I'm most interested in how to detect the presence of lowercase letters. The simplest methods would be welcome.</p>
