<p>In MLX we consider a python tree to be an arbitrarily nested collection of
|
|||
|
|
dictionaries, lists and tuples without cycles. Functions in this module that
|
|||
|
|
return python trees will be using the default python <code class="docutils literal notranslate"><span class="pre">dict</span></code>, <code class="docutils literal notranslate"><span class="pre">list</span></code> and
|
|||
|
|
<code class="docutils literal notranslate"><span class="pre">tuple</span></code> but they can usually process objects that inherit from any of these.</p>
