## Create an instance

We could create an instance of this class with:

{* ../../docs_src/dependencies/tutorial011_an_py39.py hl[18] *}

And that way we are able to "parameterize" our dependency, that now has `"bar"` inside of it, as the attribute `checker.fixed_content`.

## Use the instance as a dependency

	QueueStats       ReplicationQueueStats  `json:"queueStats"` // replication queue stats
	ProxyStats       ProxyMetric            `json:"proxyStats"`
}

// BucketReplicationStats represents inline replication statistics
// such as pending, failed and completed bytes in total for a bucket
type BucketReplicationStats struct {
	Stats map[string]*BucketReplicationStat `json:",omitempty"`
	// Completed size in bytes

/// tip

Prefer to use the `Annotated` version if possible.

Note that the parameters inside the function have their natural data type, and you can, for example, perform normal date manipulations, like:

//// tab | Python 3.10+

```Python hl_lines="18-19"

# above is tagged with "py3-none-any". We cannot change the tags by simply
# renaming the wheels as uploading to PyPI would fail with "File already exists"
# error. In order to upload to PyPI, we unpack the wheel and change the tag
# inside a metadata file to the one we want (e.g cp38-cp38-win_amd) and then
# re-pack it to generate it as a platform specific wheel with this new wheel
#tag.
python3 -m wheel unpack "${pure_python_whl}"

```Python
app.dependency_overrides = {}
```

/// tip

If you want to override a dependency only during some tests, you can set the override at the beginning of the test (inside the test function) and reset it at the end (at the end of the test function).

This will give you editor support inside of your function, with error checks, completion, etc.
