once again, probably a trivial question but i googled and didn't
get an obvious solution. how to list the attributes of a *class*?
dir(type(an_obj))
or more reliable:
list(vars(type(an_obj)))
(dir() uses __dir__ which can be implemented in any way, and default
implementation, accordinto to the docs, "attempts to produce the most
relevant, rather than complete, information").
eg., i was playing with dicts and noticed that the type returned by
the keys() method was "dict_keys". so i'm now curious as to the
attributes of the dict_keys class. but i don't know how to look at
that without first *creating* such an instance, then asking for
"dir(dk)".
Why you bother about creating an instance? Just do it:
list(vars(type({}.keys())))
or dir(type({}.keys()))
if dir() satisfies you.
