Parser Tree

The parser tree is returned by calling :py:meth:parso.Grammar.parse.

.. note:: Note that parso positions are always 1 based for lines and zero based for columns. This means the first position in a file is (1, 0).

Parser Tree Base Classes

Generally there are two types of classes you will deal with: :py:class:parso.tree.Leaf and :py:class:parso.tree.BaseNode.

.. autoclass:: parso.tree.BaseNode :show-inheritance: :members:

.. autoclass:: parso.tree.Leaf :show-inheritance: :members:

All nodes and leaves have these methods/properties:

.. autoclass:: parso.tree.NodeOrLeaf :members: :undoc-members: :show-inheritance:

Python Parser Tree

.. currentmodule:: parso.python.tree

.. automodule:: parso.python.tree :members: :undoc-members: :show-inheritance:

Utility
