Get __name__ of calling function's module in Python

Check out the inspect module:

inspect.stack() will return the stack information.

Inside a function, inspect.stack()[1] will return your caller's stack. From there, you can get more information about the caller's function name, module, etc.

See the docs for details:

http://docs.python.org/library/inspect.html

Also, Doug Hellmann has a nice writeup of the inspect module in his PyMOTW series:

http://pymotw.com/2/inspect/index.html#module-inspect

EDIT: Here's some code which does what you want, I think:

import inspect def info(msg):    frm = inspect.stack()[1]    mod = inspect.getmodule(frm[0])    print '[%s] %s' % (mod.__name__, msg)

Confronted with a similar problem, I have found that sys._current_frames() from the sys module contains interesting information that can help you, without the need to import inspect, at least in specific use cases.

>>> sys._current_frames(){4052: <frame object at 0x03200C98>}

You can then "move up" using f_back :

>>> f = sys._current_frames().values()[0]>>> # for python3: f = list(sys._current_frames().values())[0]>>> print f.f_back.f_globals['__file__']'/base/data/home/apps/apricot/1.6456165165151/caller.py'>>> print f.f_back.f_globals['__name__']'__main__'

For the filename you can also use f.f_back.f_code.co_filename, as suggested by Mark Roddy above. I am not sure of the limits and caveats of this method (multiple threads will most likely be a problem) but I intend to use it in my case.

I don't recommend do this, but you can accomplish your goal with the following method:

def caller_name():    frame=inspect.currentframe()    frame=frame.f_back.f_back    code=frame.f_code    return code.co_filename

Then update your existing method as follows:

def info(msg):    caller = caller_name()    print '[%s] %s' % (caller, msg)
