[Numpy-discussion] Creating array containing empty lists

Hi numpy people,
I have a problem with array broadcasting for object arrays and list. I
would like to create a numpy array containing empty lists (initially -
I will append to them later):
import numpy as npy
a = npy.empty((2), dtype=npy.object_)
# Works fine:
for i in range(len(a)):
a[i] = []
print a
# Does not work:
a[:] = []
a[:] = list()
Is it possible to broadcast a list to all elements of a numpy array?
Or will I have to loop through it and set the individual elements?
Best regards,
Jesper
