### Add types { #add-types }

Let's modify a single line from the previous version.

We will change exactly this fragment, the parameters of the function, from:

```Python
    first_name, last_name
```

to:

```Python
    first_name: str, last_name: str
```

That's it.

	ChecksumAlgorithm string

	// ChecksumType if set
	ChecksumType string
}

func (lm ListMultipartsInfo) Lookup(uploadID string) bool {
	for _, upload := range lm.Uploads {
		if upload.UploadID == uploadID {
			return true
		}
	}
	return false
}

// ListMultipartsInfo - represents bucket resources for incomplete multipart uploads.

                        return rangeQueryBuilder;
