Hi, I am looking for an alternative to: ************************************************************ Please consider the environment. Do you really need to print this email?
>>> listx=[[[] for k in range(ds)] for j in range(i)] as right now I am getting a Memory error on this, I tried this also on a cluster node with something like 16GB of memory and it didn't solve the problem. listx is subsequently used: >>> for x in something: >>> for y in x: >>> listx[ii][y[1]].append(y[0]) >>> ii+=1 For reference values for k range from 300 -1200 and for i ~5000. I though about using scipy/numpy array but then I wouldn't be able to have the flexibility of using append or not having to predefine the size.
