__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)
|
| Telegram channel
