How to get all the attributes in python for a class that inherits from a named_tuple

I have a python class that I inherit from a named tuple. I add another attribute to it's instance

from collections import namedtuple
class Test(namedtuple("Test", ('a', 'b', 'c', 'd', 'e'))):
     pass
T = Test(1,2,3,4,5)
T.list = [ 1,2,3,4,5,6,7,8]

So T has 6 attributes: a,b,c,d,e,list. Is there any way to print all the attributes using one command? "T.__dict" gives me just "list" attribute. "T.__fields" gives me all the namedtuple fields.

I don't think I fully understand what inheriting from namedtuple does.

Using the dir(T) command will print all the attributes (including builtin, class attributes) of T.

from collections import namedtuple
class Test(namedtuple("Test", ('a', 'b', 'c', 'd', 'e'))):
     pass
T = Test(1,2,3,4,5)
T.list = [ 1,2,3,4,5,6,7,8]
print dir(T)

output:

['add', 'class', 'contains', 'delattr', 'dict', 'doc', 'eq', 'format', 'ge', 'getattribute', 'getitem', 'getnewargs', 'getslice', 'getstate', 'gt', 'hash', 'init', 'iter', 'le', 'len', 'lt', 'module', 'mul', 'ne', 'new', 'reduce', 'reduce_ex', 'repr', 'rmul', 'setattr', 'sizeof', 'slots', 'str', 'subclasshook', '_asdict', '_fields', '_make', '_replace', 'a', 'b', 'c', 'count', 'd', 'e', 'index', 'list']
