The following code shows one way to get both function name and
argument names from inside a function using module inspect in python
2.6:

import inspect

def myfunc(arg1, arg2):
    f = inspect.currentframe()
    funcname = inspect.getframeinfo(f).function
    numargs =  f.f_code.co_argcount
    argnames = f.f_code.co_varnames[:numargs]
    print funcname, argnames

myfunc(1, "ppp")

NOTE: it does not list parameters passed as list (*args) or as dict
(**kwd).

P.S . I use this to generate automatically trace messages of type
"called myfunc( arg1=1, arg2=ppp" ).
But I currently lack  a way, from inside a method, to determine the
name of the class to which the
method belong, so I could automatically generate trace messages of
type "class.method called etc ...".
Pointers are welcome.
