## Import `Field` { #import-field }

First, you have to import it:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[4] *}


/// warning

Notice that `Field` is imported directly from `pydantic`, not from `fastapi` as are all the rest (`Query`, `Path`, `Body`, etc).

///

## Declare model attributes { #declare-model-attributes }

You can then use `Field` with model attributes:

    }

    public Map<Object, InputLocation> getLocations() {
        return locations;
    }

    /**
     * Gets the parent InputLocation where this InputLocation may have been imported from.
     * Can return {@code null}.
     *
     * @return InputLocation
     * @since 4.0.0
     */
    @Override
    public InputLocation getImportedFrom() {
        return importedFrom;
    }

    this.keyTable = keyTable;
    this.valueTable = valueTable;
    this.entries = entries;
    this.mask = mask;
    this.hashCode = hashCode;
  }

  // checkNoConflictInKeyBucket is static imported from RegularImmutableMap

  /**
   * @throws IllegalArgumentException if another entry in the bucket has the same key
   * @throws BucketOverflowException if this bucket has too many entries, which may indicate a hash

## Technical Details { #technical-details }

The class `BackgroundTasks` comes directly from <a href="https://www.starlette.io/background/" class="external-link" target="_blank">`starlette.background`</a>.

It is imported/included directly into FastAPI so that you can import it from `fastapi` and avoid accidentally importing the alternative `BackgroundTask` (without the `s` at the end) from `starlette.background`.

            "ID": "TempUploads",
            "Filter": {
                "Prefix": "temp/"
            },
            "Status": "Enabled"
        }
    ]
}

We also declare a special parameter of type `SecurityScopes`, imported from `fastapi.security`.

This `SecurityScopes` class is similar to `Request` (`Request` was used to get the request object directly).

{* ../../docs_src/security/tutorial005_an_py310.py hl[9,106] *}

We are importing the submodule `items` directly, instead of importing just its variable `router`.

This is because we also have another variable named `router` in the submodule `users`.

If we had imported one after the other, like:

```Python
from .routers.items import router
from .routers.users import router
```

```Python hl_lines="1"
{!> ../../docs_src/python_types/tutorial006.py!}
```

Declare the variable, with the same colon (`:`) syntax.

As the type, put the `List` that you imported from `typing`.

As the list is a type that contains some internal types, you put them in square brackets:

```Python hl_lines="4"
{!> ../../docs_src/python_types/tutorial006.py!}
```
