another option... another implementation:

def chop(lst,chunksize):

    x = 0
    ret = []
    while x another implementation:

<pre>
def chop(lst,chunksize):

    x = 0
    ret = []
    while x

</pre>

Not sure what happened there... ASPN seems to have mangled my post...

list comprehension (abstraction).

>>> cf= lambda s,p: [ s[i:i+p] for i in range(0,len(s),p) ]

>>> cf('1a2b3c4d5e6f',2)
['1a', '2b', '3c', '4d', '5e', '6f']

>>> cfi= iter(cf('1a2b3c4d5e6f',2))
>>> [ i for i in cfi ]
['1a', '2b', '3c', '4d', '5e', '6f']
