The classes who represent this tree, are sitting in the :mod:`parso.tree` module. The Python module ``tokenize`` is a very important part in the ``Parser``, because it splits the code into different words (tokens). Sometimes it looks a bit messy. Sorry for that! You might ask now: "Why didn't you use the ``ast`` module for this? Well, ``ast`` does a very good job understanding proper Python code, but fails to work as soon as there's a single line of broken code. There's one important optimization that needs to be known: Statements are not being parsed completely. ``Statement`` is just a representation of the tokens within the statement. This lowers memory usage and cpu time and reduces the complexity of the ``Parser`` (there's another parser sitting inside ``Statement``, which produces ``Array`` and ``Call``). )DictType)tree)ReservedStringc*a]tRt^ toRtRtRtVtR#)ParserSyntaxErrorzS Contains error information about the parser tree.
