__slots__ can be used to save memory. You can use any iterable as __slots__ value, including dict. AND Starting from Python 3.8, you can use dict to specify docstrings for slotted attributes __slots__:

class Channel:
"Telegram channel"
__slots__ = {
'slug': 'short name, without @',
'name': 'user-friendly name',
}
def __init__(self, slug, name):
self.slug = slug
self.name = name

inspect.getdoc(Channel.name)
# 'user-friendly name'

Also, help(Channel) lists docs for all slotted attributes:

class Channel(builtins.object)
| Channel(slug, name)
