To create a tree walker for a new type of tree, you need to implement a tree walker object (called TreeWalker by convention) that implements a 'serialize' method which takes a tree as sole argument and returns an iterator which generates tokens. é)Úabsolute_importÚdivisionÚunicode_literalsé)Ú constants)Ú default_etreeÚ getTreeWalkerÚpprintNcKsª| ¡}|tkr |dkr0ddlm}|jt|<np|dkrPddlm}|jt|<nP|dkrpddlm}|jt|<n0|dkr dd lm}|d krt}|j |f|ŽjSt  |¡S) a;Get a TreeWalker class for various types of tree with built-in support :arg str treeType: the name of the tree type required (case-insensitive).
