A function that knows the name of the package from which it's been called

Question

I have two packages:

• my_tools , a series tools including function f()
• my_project which has my_tools as a dependency and which is using its f() function

My problem is that when I call f() from my_project package's code, I need f() to be able to find it's been called from the my_project package (and for instance return the package's name).

For example:

# my_project/code.py
from my_tools import f
print f()  # prints 'my_project'

I've been playing around with sys and inspect but couldn't find any solution so far.

Answer 1

Use inspect.currentframe to get frame information, then check __package__ attribute of the module:

import inspect

def f():
    frame = inspect.currentframe()
    return frame.f_back.f_globals.get('__package__')
