Something like this, perhaps?

>>> mystring = "123456789ABCDEF"
>>> mylist = [mystring[x:x+3] for x in range(0,len(mystring),3)]
>>> mylist
['123', '456', '789', 'ABC', 'DEF']
>>>

Note that it's not terribly common to want to split a string in fixed width
pieces.  It's far more common that there's some sort of delimiting character
that you want to break on, and for those cases, there's the split method:

>>> mystring = "123,456,789,ABC,DEF"
>>> mylist = mystring.split(',')
>>> mylist
['123', '456', '789', 'ABC', 'DEF']
>>>

Hope that helps...
