Question

I want to create a multidimensional array with a predefined size. In C I would do the following:

int multi_array[5][6][7];

How do I create such thing in Python?

Answer 1

import numpy as np
a = np.ndarray((5,6,7), dtype=int)

note: This array will contain whatever junk happened to be in the unallocated memory at the time of creation. You may prefer to use this form if you are going to populate it with data later, for efficiency. Otherwise you might prefer to use np.zeros instead.
