foo.py:

import bar
bar.show_importer()

output:

'foo' or 'foo.py' or 'path/to/foo' etc.

Possible?

Thanks,

I think this is exactly opposite of what he was asking for.

Given than any number of modules can import other modules but each
module really only exists once in the Python object space (normally)
would mean that what the OP is asking for isn't possible.

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?

You're absolutely correct, thou shalt not post late at night when very
tired. :)
