My first thought is to use the numpy library since it is good at quickly 
creating large arrays (of any dimension) and you can easily get the data 
out as a list if you really need that (but are you sure you need that? 
You may be able to just use the numpy array directly).

It might help to have a clearer idea of why you want to do this.

P.S. numarray or Numeric would also do the job. They are older, 
deprecated numeric libraries. numpy is recommended for new code.
