В данном примере:\n\n```python\nky=42\n```\n\nPyCharm выводит, что `ky` — число (`int`). При вызове функции с `ky='b'` передается строка, что не соответствует ожидаемому типу. Это **только предупреждение статического анализатора**, а не ошибка Python — язык динамически типизированный, поэтому передача строки допустима и выполнение не прерывается.\n\n**Почему PyCharm ругается на скобки в return:**\nИногда PyCharm отмечает сложные кортежи или выражения в return, если есть подозрение на неоднозначность типов или потенциальную опечатку. Это также не ошибка интерпретатора, а подсказка IDE.\n\n**Итог:**\n\n* Программа корректно работает в Python.\n* Предупреждения PyCharm — результат статической проверки типов.\n* Чтобы убрать предупреждение, можно использовать аннотации типов явно, например:\n\n```python\ndef f(x: int, y: int, *args: int, kx=None, ky: int = 42, **kwargs):\n return (x, y, args, kx, ky, kwargs)\n```\n\nили

Это <strong>только предупреждение статического анализатора</strong>, а не ошибка Python — язык динамически типизированный, поэтому передача строки допустима и выполнение не прерывается.</p>
<p><strong>Почему PyCharm ругается на скобки в return:</strong>
Иногда PyCharm отмечает сложные кортежи или выражения в return, если есть подозрение на неоднозначность типов или потенциальную опечатку. Это также не ошибка интерпретатора, а подсказка IDE.</p>
<p><strong>Итог:</strong></p>
<ul>
<li>Программа корректно работает в Python.</li>
<li>Предупреждения PyCharm — результат статической проверки типов.</li>
<li>Чтобы убрать предупреждение, можно использовать аннотации типов явно, например:</li>
