dir() doesn't do it either:

dir( [object])
Without arguments, return the list of names in the current local
symbol table. With an argument, attempts to return a list of valid
attributes for that object. This information is gleaned from the
object's __dict__ attribute, if defined, and from the class or type
object. ***The list is not necessarily complete.*** If the object is a
module object, the list contains the names of the module's attributes.
If the object is a type or class object, the list contains the names
of its attributes, and recursively of the attributes of its bases.
Otherwise, the list contains the object's attributes' names, the names
of its class's attributes, and recursively of the attributes of its
class's base classes. The resulting list is sorted alphabetically. For
example:
Note: Because dir() is supplied primarily as a convenience for use at
an interactive prompt, it tries to supply an interesting set of names
more than it tries to supply a rigorously or consistently defined set
of names, and its detailed behavior may change across releases.

In other words, dir() is the most preposterous function in python.
