Accessing method object from within a method

[Vivek Sawant]

Hi,

Is there a way to obtain the method/function object from within the
method like 'self' refers to the object instance. I would like to avoid
looking method name (string) in class/object attributes. My goal is to
write code that need not be changed when the method name is changed.

def method (self, ...)
# somehow obtain 'methodobj' for this 'method'
mname = methodobj.__name__;
# do something with mname

Thanks.

The usual use for this is for debugging purposes, when somebody wants
to print the name of the current method. If your needs are not much
different than that, look into sys._getframe() and frame objects.

Peter,

I had browsed through documentation for frame objects earlier, but
nothing had jumped out. Here's what your suggestion helped me conjur up
and it worked:

def method (self, ...)
mname = sys._getframe(0).f_code.co_name;
# do something with mname

Is this what you had in mind or did you mean to suggest something better?

Thanks!

That's about it. By referring to frame objects, I meant to lead you to
the stuff which you found so that you could see the extent of information
aside from just function name, which is available to you. Enjoy!
