Thank you for your help. I know the function g is changed after setting the func_name. But I still can't call funciton g by using f(), when I try to do this, error will occur: <code> >>> g.func_name="f" >>> print g <function f at 0x00B2CEB0> >>> f() Traceback (most recent call last): File "<stdin>", line 1, in ? NameError: name 'f' is not defined </code> Since the name of g is changed into f, why can't I call it by using f()? Should I call it using f through other ways? Please tell me. Thanks~
