While this actually might be bad

How is this an issue ? Python's lists are not fixed-sized arrays.

That is exactly what I was looking for. I'm actually working on some
problems at http://codgolf.com. I find it helps

NB: better to avoid using builtins types and functions names as identifiers.

Please don't perpetuate this bad habit!!! "arg=[]" is evaluated at
compile time, not runtime, and will give all default-inited llists the
same underlying list.
The correct idiom is:
def __init__(self, arg = None):

The issue is that I don't know how long the list will eventually be.
Essentially I'm trying to use a 2D list to hold lines that I will
eventually print to the screen. Blank elements in the list will be
printed as spaces. I suppose every time I add an elem

I'm looking to add an element to list of items, however I'd like to
add it at a specific index greater than the current size:
list = [1,2,3]
list.insert(10,4)
What I'd like to see is something like:
[1,2,3,,4]
However I see:
[1,2,3,4]
Is there any way to produce this kind of behavior eas
