If you already know about virtual environments, how to create them and use them, you might want to skip this section. 🤓

///

/// tip

A **virtual environment** is different than an **environment variable**.

An **environment variable** is a variable in the system that can be used by programs.

         * ReflectionFreeAssertThrowsTest with a testNulls method, but that's annoying to have to do
         * for a package-private utility class. So we skip the class entirely instead.
         */
        continue;
      }
      try {
        tester.doTestNulls(classToTest, visibility);
      } catch (Throwable e) {

そして、それはすべての*path operation関数*が持っているのと同じ形と構造を持っています。

「デコレータ」を含まない（`@app.get("/some-path")`を含まない）*path operation関数*と考えることもできます。

そして何でも返すことができます。

この場合、この依存関係は以下を期待しています:

* オプショナルのクエリパラメータ`q`は`str`です。
* オプショナルのクエリパラメータ`skip`は`int`で、デフォルトは`0`です。
* オプショナルのクエリパラメータ`limit`は`int`で、デフォルトは`100`です。

そして、これらの値を含む`dict`を返します。

 *  New: Update to h2-14 and hpack-9.
 *  New: OkHttp includes a user-agent by default, like `okhttp/2.1.0-RC1`.
 *  Fix: Handle response code `308 Permanent Redirect`.
 *  Fix: Don't skip the callback if a call is canceled.
 *  Fix: Permit hostnames with underscores.
 *  Fix: Permit overriding the content-type in `OkApacheClient`.
 *  Fix: Use the socket factory for direct connections.

This section is useful only to a handful of people, team members with permissions to manage the repository. You can probably skip it. 😉

...so, you are a [team member of FastAPI](./fastapi-people.md#team){.internal-link target=_blank}? Wow, you are so cool! 😎

### Understand that Code { #understand-that-code }

The important point is just using **`AfterValidator` with a function inside `Annotated`**. Feel free to skip this part. 🤸

But if you're curious about this specific code example and you're still entertained, here are some extra details.
