title: Looking for a good Python Tree data structure
body: <p>I am looking for a good Tree data structure class. I have come across <a href="http://crablfs.sourceforge.net/tree.html" rel="noreferrer">this package</a>, but since I am relatively new to Python (not programming), I dont know if there are any better ones out there.</p>
  
  <p>I'd like to hear from the Pythonistas on here - do you have a favorite tree script that you regularly use and would recommend?</p>
  
  <p><strong>[Edit]</strong></p>
  
  <p>To clarify, by 'Tree', I mean a simple unordered tree (Hmm, thats a bit of a recursive definition - but hopefully, that clarifies things somewhat). Regarding what I need the tree for (i.e. use case). I am reading tree data from a flat file and I need to build a tree from the data and traverse all nodes in the tree.</p>
