How to create multiple instances of a class?

[Control Reset]

Hello,

How do I create multiple instances of a class?

Lets say I have :


class Node():
   def __init__(self,index):
      print "Index : %d", index


#creat multiple instances

nodes = []
for i in range (10):
  nodes[i] = Node(i)      <---


The above gives an error, saying something like arrayoutofbounds
array.

Could you please advise.

Which basically boils down to the question on how to use list.

I think   nodes = Node(i)   will work but I dont want a list in
sequence. Basically what I want is a 2D array which I can access via
an index, eg node[i][j]. How do I do this?

Please advise?

Thank you.
