954: Bump mypy from 1.9.0 to 1.10.0 r=sanders41 a=dependabot[bot] Bumps [mypy](https://github.com/python/mypy) from 1.9.0 to 1.10.0. <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>Next release</h2> <h2>Mypy 1.10</h2> <p>We’ve just uploaded mypy 1.10 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>Support TypeIs (PEP 742)</h4> <p>Mypy now supports <code>TypeIs</code> (<a href="https://peps.python.org/pep-0742/">PEP 742</a>), which allows functions to narrow the type of a value, similar to <code>isinstance()</code>. Unlike <code>TypeGuard</code>, <code>TypeIs</code> can narrow in both the <code>if</code> and <code>else</code> branches of an if statement:</p> <pre lang="python"><code>from typing_extensions import TypeIs <p>def is_str(s: object) -> TypeIs[str]: return isinstance(s, str)</p> <p>def f(o: str | int) -> None: if is_str(o): # Type of o is 'str' ... else: # Type of o is 'int' ... </code></pre></p> <p><code>TypeIs</code> will be added to the <code>typing</code> module in Python 3.13, but it can be used on earlier Python versions by importing it from <code>typing_extensions</code>.</p> <p>This feature was contributed by Jelle Zijlstra (PR <a href="https://redirect.github.com/python/mypy/pull/16898">16898</a>).</p> <h4>Support TypeVar Defaults (PEP 696)</h4> <p><a href="https://peps.python.org/pep-0696/">PEP 696</a> adds support for type parameter defaults. Example:</p> <pre lang="python"><code>from typing import Generic from typing_extensions import TypeVar <p></tr></table> </code></pre></p> </blockquote> <p>...
