Python globals and keyword arguments

Why does test2() below print "True False"? I would expect "False False".

I expect test2() to change the global value EC to be False, so ec should also be False.

Why not?

Is there a straightforward way to get the "False False" behavior?

EC = True    def test1(ec=EC):      print(ec, EC)    def test2():        global EC      EC=False        test1()
