Is this a homework assignment?

A list of lists seems like the appropriate way to represent this, 
especially since it is not actually a square array.

Here is a simpler example that might give you some ideas:
In [5]: b=[]

In [6]: for i in range(5):
    ...:     b.append(range(i))
    ...:
    ...:

In [7]: b
Out[7]: [[], [0], [0, 1], [0, 1, 2], [0, 1, 2, 3]]
