I wrote some Python code which works but Pylint doesn't like the star. It keeps telling me:

```
Used * or ** magic (star-args)

```

Is it possible to write my code without the star? Some info: I'm using [lxml](http://lxml.de/); self.xml is an [objectified](http://lxml.de/objectify.html) XML file.

```
@property
def version_string(self):
    '''Return the version as a string.'''
    try:
        version_format = self.xml.version.get("format")
    except AttributeError:
        return None
    version_values = (v.text for v in self.xml.version.v)
    return version_format.format(*version_values)

```
