In CPython, it is possible to get a handle on a function from within a
function and from that gets its *definition* name (the one in the def
statement), but you are asking about the names bound to the function
..

I do not believe this is sanely possible.  (Insanely would be getting
the code and line number of the calling context, decompiling the code
and using the linenum to find the call and from that the calling name,
if there is one.

You left out the possibility of calling a function without a name or
without it even having any bound names left.

def f(): print 'hi'

fl = [f]
del f
fl[0]()
# prints
hi
