I don't think so. Your question isn't even well-defined. Given three 
modules:

# a.py
import b
import d

# b.py
import d

# c.py
import a
import d
import b
print d.show_importer()

and you run c.py, what do you expect d.show_importer() to return?

And what about "from d import show_importer" -- does that count as 
"importing d"?

Why do you think that a module needs to know what other modules imported 
it? I can't imagine why this would be necessary, what are you intending 
to do with it?
