Is it possible to call a class but without a new instance created?

No, I don't have any specific application in mind. This idea was just
triggered by a sentence in a Docstring in file font.py.

class Font:
     """Represents a named font.
     Constructor options are:
     ...
     exists -- does a named font by this name already exist?
        Creates a new named font if False, points to the existing font 
if True.
     ...
     """

But honestly I still don't know how it "points to the existing font":-(
