Hi,
Am I missing something or don't classes know how they're called
(unlike funcs, which have a __name__ attribute, very practicle)? Is
there a way to get it otherwise?
The class has it, the instance doesn't. That said, you are looking for
self.__class__.__name__ ...
class SuperType:
# ...
def __repr__ (sef):
return "%s(stuff)" % (self.__class__.__name__, stuff)
... which you do use here.
Well, this was not real code, but an example of what I wished to be able to
write!
But I need each class to know its name. Subtypes are actually
defined by users (of a lib), presently they are forced to write the
name explicitely, which is stupid since they already give it as var
name:
class SubType (SuperType):
__name__ = "SubType"
# ....
I do not get it. The __class__.__name__ thing works great for me:
>>> class Foo():
... def whoami(self):
... return self.__class__.__name__
...
>>> f = Foo()
>>> f.whoami()
'Foo'
>>> class Bar(Foo):
... pass
...
>>> b = Bar()
>>> b.whoami()
'Bar'
Please be a bit more specific about your problem, because the problem
you described obviously does not exist ;).
I just missed it. Sorry!
In fact, I did:
class C: pass
...
dir(C)
['__class__', '__delattr__', '__dict__', '__dir__', '__doc__', '__eq__',
'__format__', '__ge__', '__getattribute__', '__gt__', '__hash__', '__init__',
'__le__', '__lt__', '__module__', '__ne__', '__new__', '__reduce__',
'__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__',
'__subclasshook__', '__weakref__']
No __name__, or am I blind? But:
C.__name__
'C'
Still, there is a __name__.
???
Compare with:
def f(): pass
...
dir(f)
['__annotations__', '__call__', '__class__', '__closure__', '__code__',
'__defaults__', '__delattr__', '__dict__', '__dir__', '__doc__', '__eq__',
'__format__', '__ge__', '__get__', '__getattribute__', '__globals__', '__gt__',
'__hash__', '__init__', '__kwdefaults__', '__le__', '__lt__', '__module__',
'__name__', '__ne__', '__new__', '__qualname__', '__reduce__', '__reduce_ex__',
'__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__']
Here I can see __name__ (thus, I'm probably not that blind yet ;-).
