@ -126,16 +126,33 @@ The abstract grammar is currently defined as follows:
|
|||
Apart from the node classes, the :mod:`ast` module defines these utility functions
|
||||
and classes for traversing abstract syntax trees:
|
||||
|
||||
.. function:: parse(source, filename='<unknown>', mode='exec')
|
||||
.. function:: parse(source, filename='<unknown>', mode='exec', *, type_comments=False)
|
||||
|
||||
Parse the source into an AST node. Equivalent to ``compile(source,
|
||||
filename, mode, ast.PyCF_ONLY_AST)``.
|
||||
|
||||
If ``type_comments=True`` is given, the parser is modified to check
|
||||
and return type comments as specified by :pep:`484` and :pep:`526`.
|
||||
This is equivalent to adding :data:`ast.PyCF_TYPE_COMMENTS` to the
|
||||
flags passed to :func:`compile()`. This will report syntax errors
|
||||
for misplaced type comments. Without this flag, type comments will
|
||||
be ignored, and the ``type_comment`` field on selected AST nodes
|
||||
will always be ``None``. In addition, the locations of ``# type:
|
||||
ignore`` comments will be returned as the ``type_ignores``
|
||||
attribute of :class:`Module` (otherwise it is always an empty list).
|
||||
|
||||
In addition, if ``mode`` is ``'func_type'``, the input syntax is
|
||||
modified to correspond to :pep:`484` "signature type comments",
|
||||
e.g. ``(str, int) -> List[str]``.
|
||||
|
||||
.. warning::
|
||||
It is possible to crash the Python interpreter with a
|
||||
sufficiently large/complex string due to stack depth limitations
|
||||
in Python's AST compiler.
|
||||
|
||||
.. versionchanged:: 3.8
|
||||
Added ``type_comments=True`` and ``mode='func_type'``.
