Python 2.7 creating a multidimensional list

i found this:

Matrix = [[0 for x in xrange(5)] for x in xrange(5)]

You can now add items to the list:

Matrix[0][0] = 1
Matrix[4][0] = 5

print Matrix[0][0] # prints 1
print Matrix[4][0] # prints 5

from here: How to define two-dimensional array in python

looks like the most easiest way is as follows:

def create_empty_array_of_shape(shape):
    if shape: return [create_empty_array_of_shape(shape[1:]) for i in xrange(shape[0])]

it's work for me

I think your list comprehension versions were very close to working. You don't need to do any list multiplication (which doesn't work with empty lists anyway). Here's a working version:

>>> y = [[[] for i in range(n)] for i in range(n)]
>>> print y
[[[], [], [], []], [[], [], [], []], [[], [], [], []], [[], [], [], []]]

A very simple and elegant way is:

a = [([0] * 5) for i in range(5)]
a
[[0, 0, 0, 0, 0], [0, 0, 0, 0, 0], [0, 0, 0, 0, 0], [0, 0, 0, 0, 0], [0, 0, 0, 0, 0]]
