[Tutor] List weirdness

[Moos Heintzen]

Hi,
I was wondering why this happens. I was trying to create a list of lists.

 >>> d = [[]]
 >>> d[0][0]=1
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
IndexError: list assignment index out of range
 >>> d
[[]]

What's wrong with that?

However:
 >>> d[0].append(1)
 >>> d
[[1]]

I guess I can't reference [0] on an empty list. (I come from a C 
background.)
