So you have:

import my.module
theclass = my.module.Foo
print tellme(theClass)

and you want to know how to write tellme?  Why not just change it to
take a string, and pass it  "my.module.Foo" ?

If you have stored the class away somewhere, and want to figure it out
from there, you could look at the __module__ attribute.  that'll tell
you the module name, but not the class name.

If you're really asking how to get that string from an INSTANCE of the
class, then try the __class__ attribute of that instance.
