title: Python find the minimum using for loops?
body: <p>I don't know how to make python "scan" through the list for a candidate and then go back to the loop again to find another candidate for the min.</p>
  
  <pre><code>    candidate = 0
      maximum = 0
      a = [12, 10, 50, 100, 24]
      for i in len(s):
          for j in range(len(s)):
  </code></pre>
