Question

Assuming I have two Python modules and path_b is in the import path:

# file: path_b/my_module.py
print "I was imported from ???"

#file: path_a/app.py
import my_module

Is it possible to see where the module is imported from? I want an output like “I was imported from path_a/app.py”, if I start app.py (because I need the file name).

Edit:
For better understanding; I could write:

# file: path_b/my_module.py
def foo(file):
    print "I was imported from %s" % file

#file: path_a/app.py
import my_module
my_module.foo(__file__)

So the output would be:

$> python path_app.py
I was imported from path_a/app.py

There may be an easier way to do this, but this works:

import inspect

print(inspect.getframeinfo(inspect.getouterframes(inspect.currentframe())[1][0])[0])

Note that the path will be printed relative to the current working directory if it’s a parent directory of the script location.
