title: Can't make a while loop run for the entire list
body: <p>Im not sure how I can run the while loop until it has checked the entire list.</p>
  <p>I have this but it just stops after it finds the first number.</p>
  <pre><code>numbers = [23,76,45,71,98,23,65,37,93,71,37,21]
  target = 71
  counter = 0
  found = False
  runtime = 0
  
  while runtime &lt; 13:
    while found == False:
      if numbers[counter] == target:
        found = True
      else:
        counter = counter + 1
    runtime = runtime + 1
  
  if found == True:
    print(&quot;Found at position&quot; , counter)
  else:
    print(&quot;No match found&quot;)
  </code></pre>
