Type annotations
^^^^^^^^^^^^^^^^

.. class:: TypeIgnore(lineno, tag)

A ``# type: ignore`` comment located at *lineno*.
*tag* is the optional tag specified by the form ``# type: ignore <tag>``.

.. doctest::

>>> print(ast.dump(ast.parse('x = 1 # type: ignore', type_comments=True), indent=4))
Module(
body=[
Assign(
targets=[
Name(id='x', ctx=Store())],
value=Constant(value=1))],
type_ignores=[
TypeIgnore(lineno=1, tag='')])
>>> print(ast.dump(ast.parse('x: bool = 1 # type: ignore[assignment]', type_comments=True), indent=4))
Module(
body=[
AnnAssign(
target=Name(id='x', ctx=Store()),
annotation=Name(id='bool', ctx=Load()),
value=Constant(value=1),
simple=1)],
type_ignores=[
TypeIgnore(lineno=1, tag='[assignment]')])

.. note::
:class:`!TypeIgnore` nodes are not generated when the *type_comments* parameter
is set to ``False`` (default). See :func:`ast.parse` for more details.
