python-find-function cannot work as the emacs.location_of function is
missing from etc/emacs[23].py
The following seems to work for Python 2.x

def location_of (name, imports):
    """Get location at which NAME is defined (or nil).
    Provides a pair (PATH, LINE), where LINE is the start of the definition
    in path name PATH.
    Exec IMPORTS first."""
    locls = {}
    if imports:
        try: exec (imports, locls)
        except: pass
    try:
        obj = eval (name, globals (), locls)
        # Bug: (in Python 2.5) `getsourcefile' only works with modules,
        # hence the `getmodule' here.
        srcfile = inspect.getsourcefile (inspect.getmodule (obj))
        _, line = inspect.getsourcelines (obj)
        print '_emacs_out ("%s" . %d)' % (srcfile.replace('\\', '/'), line)
    except:
        print "_emacs_out ()"


Couple comments:
- it isn't mine, was simply adapted from
http://www.loveshack.ukfsn.org/emacs/emacs.py
- .replace('\\', '/') seems necessary on Windows but feels like an ugly hack

Version: 24.2

Thanks for the report. The Emacs trunk has a new python.el, and it seems
your problem is fixed there. This should appear in Emacs 24.2.

python-find-function is replaced by python-nav-jump-to-defun.
