title: C++ Structure within itself?
body: <p>I've been trying to port this code to python, but there is something I do not quite understand in C++ (I do know a bit of C++ but this is beyond me):</p>
  
  <pre><code>typedef struct huffnode_s
  {
      struct huffnode_s *zero;
      struct huffnode_s *one;
      unsigned char val;
      float freq;
  } huffnode_t;
  </code></pre>
  
  <p>What I don't get is how huffnode_s can be within itself, I've never seen this before and don't quite understand it. What does this mean, and if someone can, what would be the python equivalent?</p>
