## Check the username { #check-the-username }

Here's a more complete example.

Use a dependency to check if the username and password are correct.

	// Set a unique 'uuid' for this disk, only used when
	// disk is replaced and formatted.
	SetDiskID(id string)

	// Returns healing information for a newly replaced disk,
	// returns 'nil' once healing is complete or if the disk
	// has never been replaced.
	Healing() *healingTracker
	DiskInfo(ctx context.Context, opts DiskInfoOptions) (info DiskInfo, err error)

```

...to:

```Python
        ... "item_price": item.price ...
```

...and see how your editor will auto-complete the attributes and know their types:
