instance method questions

[Danny]

howdy,

I have created an instance method for an object using new.instancemethod. It
works great. Now the questions are:

1) how do I dynamically inspect an object to determine if it has an instance
method? (there is a class method with the same name)

2) how do I dynamically delete the instance method?

thanks,
Danny

class Foo:
def foo(self):
pass

x = Foo()

import types

Why would you want to do that?

Here is a way that relies on an implementation detail of current CPython:
.... def foo(self): pass
.... def __init__(self):
.... import new
.... def bar(self): pass
.... self.foo = new.instancemethod(bar, self)
....False

This alternative is a little less subtle:
False
