def isinstancemethod(cls, obj):

    ''''Returns `True` if the given object is an instance method of the class
    it is defined on (as opposed to a `staticmethod` or a `classmethod`).
    This requires both the class the object is a member of as well as the
    object itself in order to make this determination.
    Parameters
    cls : `type`
    The class on which this method was defined.
    obj : `object`
    A member of the provided class (the membership is not checked directly,
    but this function will always return `False` if the given object is not
    a member of the given class).
    Examples
    >>> from astropy.extern import six
    >>> class MetaClass(type):
    ...     def a_classmethod(cls): pass
    >>> @six.add_metaclass(MetaClass)
    ... class MyClass(object):
    ...     __metaclass__ = MetaClass
    ...     def an_instancemethod(self): pass
    ...     @classmethod
    ...     def another_classmethod(cls): pass
    ...     @staticmethod
    ...     def a_staticmethod(): pass
    >>> isinstancemethod(MyClass, MyClass.a_classmethod)
    False
    >>> isinstancemethod(MyClass, MyClass.another_classmethod)
    False
    >>> isinstancemethod(MyClass, MyClass.a_staticmethod)
    False
    >>> isinstancemethod(MyClass, MyClass.an_instancemethod)
    True'
