Of course it doesn't, for the same reason that your first attempt didn't work
either. You've made a copy of an array and put the copy into the dictionary,
then made copies of that dictionary. The process of making copies of the
dictionary doesn't make copies of the objects it contains.

import copy
d1 = {1: array([2, 3, 4]), 2: ''}
l1 = []
for i in range(3):
l1.append(copy.deepcopy(d1))
