I tried the (as I thought) nice compact form
In [60]: a,b = (zeros((2,)),)*2
But...
In [61]: b[0] = 2
In [62]: a
Out[62]: array([ 2., 0.])
a and b are the _same_ array
But
In [68]: a,b = (zeros((2,)),zeros((2,)))
In [69]: b[0] = 2
In [70]: a
Out[70]: array([ 0., 0.])
is OK. a & b are

Correct.

a, b = [zeros((2,)) for x in range
It's not a question of tuple, you made a tuple, but in each element, you put
the same array, so this behaviour is to be expected.
