The latter. But why don't you try it yourself by putting a 

print "importing module" # you will see that once

statement in the module? 

There is one notable exception, the application's main module:

$ cat main.py
import main
print "importing main as", __name__
$ python main.py
importing main as main
importing main as __main__
