I think you're right that the meaning of list-int multiplication can't/shouldn't be changed if this way. A multidimensional list comprehension would be useful even for people who are using numpy as it's common to use a list comprehension to initialise a numpy array. A more modest addition for the limited case described in this thread could be to use exponentiation: >>> [0] ** (2, 3) [[0, 0, 0], [0, 0, 0]] Oscar
