dir([object])

Returns test

object

optional

REMARKS

* No prefix required - Core
* Without arguments, return the list of names in the current local scope. With an argument, attempt to return a list of valid attributes for that object.
* If the object has a method named __dir__(), this method will be called and must return the list of attributes. This allows objects that implement a custom __getattr__() or __getattribute__() function to customize the way dir() reports their attributes.
* If the object does not provide __dir__(), the function tries its best to gather information from the object's __dict__ attribute, if defined, and from its type object. The resulting list is not necessarily complete and may be inaccurate when the object has a custom __getattr__().
* The default dir() mechanism behaves differently with different types of objects, as it attempts to produce the most relevant, rather than complete, information:
* 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.
* 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. For example, metaclass attributes are not in the result list when the argument is a class.
