941: Bump mypy from 1.8.0 to 1.9.0 r=curquiza a=dependabot[bot] Bumps [mypy](https://github.com/python/mypy) from 1.8.0 to 1.9.0. <details> <summary>Changelog</summary> <p><em>Sourced from <a href="https://github.com/python/mypy/blob/master/CHANGELOG.md">mypy's changelog</a>.</em></p> <blockquote> <h1>Mypy Release Notes</h1> <h2>Mypy 1.9</h2> <p>We’ve just uploaded mypy 1.9 to the Python Package Index (<a href="https://pypi.org/project/mypy/">PyPI</a>). Mypy is a static type checker for Python. This release includes new features, performance improvements and bug fixes. You can install it as follows:</p> <pre><code>python3 -m pip install -U mypy </code></pre> <p>You can read the full documentation for this release on <a href="http://mypy.readthedocs.io">Read the Docs</a>.</p> <h4>Breaking Changes</h4> <p>Because the version of typeshed we use in mypy 1.9 doesn't support 3.7, neither does mypy 1.9. (Jared Hance, PR <a href="https://redirect.github.com/python/mypy/pull/16883">16883</a>)</p> <p>We are planning to enable <a href="https://mypy.readthedocs.io/en/stable/command_line.html#cmdoption-mypy-local-partial-types">local partial types</a> (enabled via the <code>--local-partial-types</code> flag) later this year by default. This change was announced years ago, but now it's finally happening. This is a major backward-incompatible change, so we'll probably include it as part of the upcoming mypy 2.0 release. This makes daemon and non-daemon mypy runs have the same behavior by default.</p> <p>Local partial types can also be enabled in the mypy config file:</p> <pre><code>local_partial_types = True </code></pre> <p>We are looking at providing a tool to make it easier to migrate projects to use <code>--local-partial-types</code>, but it's not yet clear whether this is practical. The migration usually involves adding some explicit type annotations to module-level and class-level variables.</p> <h4>Basic Support for Type Parameter Defaults (PEP 696)</h4> <p>This release contains new experimental support for type parameter defaults (<a href="https://peps.python.org/pep-0696">PEP 696</a>). Please try it out! This feature was contributed by Marc Mueller.</p> <p>Since this feature will be officially introduced in the next Python feature release (3.13), you will need to import <code>TypeVar</code>, <code>ParamSpec</code> or <code>TypeVarTuple</code> from <code>typing_extensions</code> to use defaults for now.</p> <p>This example adapted from the PEP defines a default for <code>BotT</code>:</p> <pre lang="python"><code>from typing import Generic from typing_extensions import TypeVar <p>class Bot: ...</p> <p>BotT = TypeVar("BotT", bound=Bot, default=Bot) </tr></table> </code></pre></p> </blockquote> <p>...
