Let's say you have a file structure like this:

```
.
├── app
│   ├── __init__.py
│   ├── main.py
│   ├── dependencies.py
│   └── routers
│   │   ├── __init__.py
│   │   ├── items.py
│   │   └── users.py
│   └── internal
│       ├── __init__.py
│       └── admin.py
```

!!! tip
    There are several `__init__.py` files: one in each directory or subdirectory.

                            },
                        },
                    },

## 一个文件结构示例

假设你的文件结构如下：

```
.
├── app
│   ├── __init__.py
│   ├── main.py
│   ├── dependencies.py
│   └── routers
│   │   ├── __init__.py
│   │   ├── items.py
│   │   └── users.py
│   └── internal
│       ├── __init__.py
│       └── admin.py
```

!!! tip
    上面有几个 `__init__.py` 文件：每个目录或子目录中都有一个。

    这就是能将代码从一个文件导入到另一个文件的原因。

    例如，在 `app/main.py` 中，你可以有如下一行：

                }
            },
            "/path_example/{item_id}": {
                "get": {
                    "summary": "Path Example",
                    "operationId": "path_example_path_example__item_id__get",
                    "parameters": [
                        {
                            "required": True,
                            "schema": {"title": "Item Id", "type": "string"},
