Here's one way:

>>> some_list = [1,1,1,2,2,2,3,3,3]
>>> unique_list = []
>>> for item in some_list:
... 	if item not in unique_list:
... 		unique_list.append(item)
... 		
>>> unique_list
[1, 2, 3]
>>>

If you are using Python 2.4 or higher:

>>> set(some_list)

A set can contain only unique elements. A set can be converted back to a list.

I would do something like this:

a = [1,1,1,1,2,3,3,3,3,4]
b = {}
for aa in a:
 b[aa] = 1
print b.keys()
