Here's what I have in my PYTHONSTARTUP file:

def hotprofile(func, *args):
    import os, tempfile
    from hotshot import Profile, stats
    filename = tempfile.mktemp(".hotshot")
    p = Profile(filename)
    result = p.runcall(func, *args)
    p.close()
    s = stats.load(filename)
    s.strip_dirs().sort_stats("cumulative").print_stats()
    print
    s.strip_dirs().sort_stats("time").print_stats()
    os.unlink(filename)
    return result
