Caller and Callee (Python recipe) by Deepak
Forked from Recipe 576925 (calleeee)
ActiveState Code (http://code.activestate.com/recipes/578483/)

A recipe to find out which function is the caller of the current function.

The caller function can be helpful for debugging — if there is no real debugger available. In terms of software engineering (loose coupling etc.) this should not be used in production code though.

import inspect

def callee():
    return inspect.getouterframes(inspect.currentframe())[1][1:4]

def caller():
    return inspect.getouterframes(inspect.currentframe())[2][1:4]

Example usage:

def anyfunction():
    print "Function %s called from function %s" % (callee(), caller())

def anotherfunction():
    anyfunction()

anotherfunction()

Output:

Function ('/tmp/caller.py', 11, 'anyfunction') called from function ('/tmp/caller.py', 14, 'anotherfunction')
