Please explain to me this code of taking sub menu nav and putting it in wp

<?php
  if($post->post_parent) {
  $children = wp_list_pages("title_li=&child_of=".$post->post_parent."&echo=0");
  $titlenamer = get_the_title($post->post_parent);
  }

  else {
  $children = wp_list_pages("title_li=&child_of=".$post->ID."&echo=0");
  $titlenamer = get_the_title($post->ID);
  }
  if ($children) { ?>

  <h2> <?php echo $titlenamer; ?> </h2>
  <ul>
  <?php echo $children; ?>
  </ul>

I'll challenge you to figure out how to find your answer on your own. You know these functions live in the WP codex, between that and your knowledge of php you should be able to get the understanding of what the functions are receiving, and what they are returning.

Take a stab at it and let me know.
