New submission from Bruce Frederiksen <>:

The python CLI always sets the __file__ variable, whether run as:

$ python


$ python -m foobar


$ python
>>> import foobar   # __file__ set in foobar module

The idle program sets the __file__ variable properly when you do the import 
from the idle shell, but __file__ is not set with the "Run Module" (F5) command 
from the editor.

I've included a patch file to set __file__, but it doesn't del it after the 
module has run.  But maybe this is OK, because the os.chdir is not undone
