getting the function name

[beliavsky at aol.com]

Is there a way in Python to print the name of the function one is
currently in?
The code

def foo():
    debug = True
    if (debug):
        print "entered",__name__

x = foo()

outputs "entered __main__"

I want to print "entered foo". Of course I could just hard-code the
string "foo" in a print statement, but I don't want to have the
function name written in more than one place.
