What you have works fine for me:

Python 2.4.1 (#2, Mar 31 2005, 00:05:10)
[GCC 3.3 20030304 (Apple Computer, Inc. build 1666)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> class MultipleRegression:
...    def __init__(self, dbh, regressors, fund):
...        self.dbh = dbh
...        self.regressors = regressors
...
>>> spam = MultipleRegression('dbh', [1,2,3,4], 5)
>>> spam.regressors
[1, 2, 3, 4]

What makes you think you only have the first member of the list? Can
you show us the code that's not working?
