This would be useful if you want to receive keys that you don't already know.

---

Another useful case is when you want to have keys of another type (e.g., `int`).

That's what we are going to see here.

In this case, you would accept any `dict` as long as it has `int` keys with `float` values:

{* ../../docs_src/body_nested_models/tutorial009_py39.py hl[7] *}

/// tip

---

Другой полезный случай — когда вы хотите, чтобы ключи были другого типа данных, например, `int`.

Именно это мы сейчас и увидим здесь.

В этом случае вы принимаете любой `dict`, пока у него есть ключи типа `int` со значениями типа `float`:

{* ../../docs_src/body_nested_models/tutorial009_py39.py hl[7] *}

/// tip | Совет

    E e = (E) t;
    int unused = comparator().compare(e, e);
    return t;
  }

  public boolean equals(@Nullable Object obj) {
