isinstancemethod

astropy.utils.introspection.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:

clstype

The class on which this method was defined.

objobject

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

>>> class MetaClass(type):
...     def a_classmethod(cls): pass
...
>>> class MyClass(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
