Didn't it work with append()? You're right - append is what you're after:

Python 2.1 (#8, Aug 22 2001, 16:46:14) 
[GCC 2.95.2 20000220 (Debian GNU/Linux)] on linux2
Type "copyright", "credits" or "license" for more information.
>>> foo = []
>>> foo[0] = 'hello'
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
IndexError: list assignment index out of range
>>> foo       
[]
>>> foo.append('world')
>>> foo
['world']
