BuiltinFunctionType.__self__

[Jacek Generowicz]

Where can I find information on the __self__ attribute of builtin
functions ?

Where can I find information on the __self__ attribute of builtin
functions ?

it's the same thing as im_self, but for methods/functions
implemented in C.

that is, if "x" is a bound method, "x.__self__" is the object
that method is bound to:

x = ["spam"]
x.count

dir(x.count)

['__call__', '__class__', '__cmp__', '__delattr__', '__doc__', '__getattribute__',
'__hash__', '__init__', '__module__', '__name__', '__new__', '__reduce__',
'__reduce_ex__', '__repr__', '__self__', '__setattr__', '__str__']['spam']

for unbound methods (and functions), it's set to None.
