Cela peut également éviter toute confusion pour les nouveaux développeurs qui voient un paramètre inutilisé dans votre code et pourraient penser qu'il est superflu.

# 调试 { #debugging }

你可以在编辑器中连接调试器，例如使用 Visual Studio Code 或 PyCharm。

## 调用 `uvicorn` { #call-uvicorn }

在你的 FastAPI 应用中直接导入 `uvicorn` 并运行：

{* ../../docs_src/debugging/tutorial001_py310.py hl[1,15] *}

### 关于 `__name__ == "__main__"` { #about-name-main }

`__name__ == "__main__"` 的主要目的是使用以下代码调用文件时执行一些代码：

<div class="termy">

```console
$ python myapp.py
```

</div>

而当其它文件导入它时并不会被调用，像这样：

```Python

	columns := make([]string, 0, len(mapValues))

	// when the length of mapValues is zero,return directly here
	// no need to call stmt.SelectAndOmitColumns method
	if len(mapValues) == 0 {
		stmt.AddError(gorm.ErrEmptySlice)
		return
	}

	var (
		result                    = make(map[string][]interface{}, len(mapValues))

// for os.OpenFile().
func LockedOpenFile(path string, flag int, perm os.FileMode) (*LockedFile, error) {

}

// Open - Call os.OpenFile
func Open(path string, flag int, perm os.FileMode) (*os.File, error) {
	return os.OpenFile(path, flag, perm)
