I'm trying to understand what you want to do, but I'm afraid it's still not clear, so I'm sorry if that reply doesn't help either. It looks to me as if you first want to convert your list of lists into a list of arrays, then iterate through this list of arrays. If that's it, then you can just do: def p(option_lists): list_of_arrays = map(numpy.array, option_lists) for my_array in list_of_arrays: ... # Do some operation on array 'my_array' -=- Olivier 2011/9/20 DIPO ELEGBEDE <dipo.elegbede@gmail.com>

I think that should sort it.

def p(option_lists): for option_list in option_lists: array = numpy.array(option_list) for i in array: print i

the option_lists here is the list of lists looping through it and then converting it into a numpy array is quiet easy.

If I try to loop through the array as you adviced, it prints out the whole items in the array.

You could also try that out.

What I am trying to achieve however is to loop through the 12 arrays and get them one after the other, doing something like:

for my_array in list_of_arrays: print my_array[0]

Hope this is clear enough. Thanks for your patience.

Olivier, the code you sent did so much magic and I'm definitely using that.

What baffles me is that looping through the 12 arrays seem impossible. I have tried what you just sent but it won't just work. You could confirm this. Sent from my BlackBerry wireless device from MTN
