You can do it using array module. array module is part of python standard library:

from array import array
from itertools import repeat

a = array("i", repeat(0, 10))
# or
a = array("i", [0]*10)

repeat function repeats 0 value 10 times. It's more memory efficient than [0]*10, since it doesn't allocate memory, but repeats returning the same number x number of times.
