/// note

La commande `uvicorn main:app` fait référence à :

* `main` : le fichier `main.py` (le module Python).
* `app` : l'objet créé dans `main.py` via la ligne `app = FastAPI()`.
* `--reload` : l'option disant à uvicorn de redémarrer le serveur à chaque changement du code. À ne pas utiliser en production !

         * So this is probably just the "Windows Java 8" case. In that case, if we wanted *another*
         * layer of fallback before consulting the system property, we could try
         * com.sun.security.auth.module.NTSystem.
         *
         * But for now, we use the value from the system property as our best guess.

from .routers import items, users
```

第二个版本是「绝对导入」：

```Python
from app.routers import items, users
```

### 避免名称冲突

我们将直接导入 `items` 子模块，而不是仅导入其 `router` 变量。

这是因为我们在 `users` 子模块中也有另一个名为 `router` 的变量。

如果我们一个接一个地导入，例如：

```Python

    - path: _test\.go$|^tests/|^samples/
      linters:
        - errcheck
        - maligned
    - path: _test\.go$
      text: "dot-imports: should not use dot imports"
    # We need to use the deprecated module since the jsonpb replacement is not backwards compatible.
    - linters:
        - staticcheck
      text: "SA1019: package github.com/golang/protobuf/jsonpb"
    - linters:
        - staticcheck

  ** since Maven 3.5.0, if <<<project.directory>>> POM property value is defined, it is used instead of artifact id:
  this permits default inheritance calculations when module directory name is not equal to artifact id. Notice that this
  property is not inherited from a POM to its child: child's POM will use child artifact id if property is not
  set.

    size.
*   TensorFlow 1.15 contains a complete implementation of the 2.0 API in its
    `compat.v2` module. It contains a copy of the 1.15 main module (without
    `contrib`) in the `compat.v1` module. TensorFlow 1.15 is able to emulate 2.0
    behavior using the `enable_v2_behavior()` function. This enables writing
    forward compatible code: by explicitly importing either

a Contributor if it was added to the Program by such Contributor itself or
anyone acting on such Contributor's behalf. Contributions do not include additions
to the Program which: (i) are separate modules of software distributed in
conjunction with the Program under their own license agreement, and (ii) are
not derivative works of the Program.

   "Contributor" means any person or entity that distributes the Program.
