For multi-dimension python lists (heterogeneous contents), use list
comprehensions to initialize the list

  dim1, dim2 = 3,5
  multi = [ [ 0 for col in range(dim2)] for row in range(dim1) ]

if you have homogeneous lists of numbers, and efficiency matters,
you should take a look at Numeric http://www.pfdubois.com/numpy, eg, 

  from Numeric import zeros, Float
  a = zeros( (dim1, dim2), Float)
