newbie question - python lists

[lee]

hi,

rfids= ['01','02']
i = 01
row = {}
items = []
for rfid in rfids:

    brains = ['1','2']

    if brains:
        for brain in brains:
            # this loop must run only once for each value of i
            row['itemnos'] = 'item_0'+str(i)+'s'
            print 'hi'
            items.append(row)
            print items
            break
    i=i+1

the above code produces output a:
[{'itemnos': 'item_02s'}, {'itemnos': 'item_02s'}]
but i want it to be,
[{'itemnos': 'item_01s'}, {'itemnos': 'item_02s'}]

can anyone point wer am erroring.
Thanks in advance.
