Accessing tag data quality using python

Is this possible?

Looking at the documentation, only tag value seems available.

I could use such a feature in case where there’s a group of components,
because expressions and indirect tags don’t support relative referring
of components, for which I’m turning to using event handlers to
update the tag values into components rather than using tag bindings.

From the documentation:

So…x=system.tag.getTagValue("[]TagName.Quality")

Right, thanks!
