How to display all the methods supported by an instance using dir( )..please hel

[Learn Python]

hi all,
i'm a begginer in python,
This is what i have:

class test:
def __init__(self):
   self.data = 100
def func(self):
   pass
if __name__ == '__main__':
t = test()
dir(t) ==> i want this to list data and func

But it does'nt list func :-(. What methods s'd i provide in addition so that 
dir( ) can recognize func() which happens to be a instance method attribute? 
I guess this s'd be possible bcos when i say
l = [] and then dir(l), i get all the list attributes. I want the same kind 
of behaviour for my class instance as well.

thanks in advance
karthik.
