Please rename files so there are no repeats. For example, README.md and
Readme.md would be the same file on Windows. In this test, you would get a
warning for "readme.md" because it makes everything lowercase. There are
repeats of these filename(s) with different casing:

 * the public API of {@code UniAddress} and its behaviour when provided
 * with different kinds of inputs.  Many static helpers in {@code
 * UniAddress} are network dependent and therefore not exercised here – they

 * that are observable without network access.

FastAPI will make sure it's run correctly so that it doesn't block the event loop.

As in this case the function is not async, the right return type would be `Iterable[Item]`:

{* ../../docs_src/server_sent_events/tutorial001_py310.py ln[28:31] hl[29] *}

### No Return Type { #no-return-type }

 *   <li>A class which implements {@code Comparable<UnrelatedType>} is very broken, and will cause
 *       undefined horrible things to happen in {@code Range}. For now, the Range API does not
 *       prevent its use, because this would also rule out all ungenerified (pre-JDK1.5) data types.
 *       <b>This may change in the future.</b>
 * </ul>

 * <h3>Other notes</h3>
 *
 * <ul>
 *   <li>All ranges are shallow-immutable.

                # explicit default status_code, and to extract it from them, instead of
                # doing this inspection tricks, that would probably be in the future

例如，你可以建立一個名為 `main.py` 的檔案，其中包含以下內容：

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```

/// tip

第二個參數是 [`os.getenv()`](https://docs.python.org/3.8/library/os.html#os.getenv) 的預設回傳值。

如果沒有提供，預設值為 `None`，這裡我們提供 `"World"` 作為預設值。

然後你可以呼叫這個 Python 程式：
