Nice.
While we are at it, why not:
class splitUp(object):
def __init__(self,src):
self._src=list(src)
def slice(self, lens):
ret = []
cur = 0
for length in lens:
if length is not None:
ret.append( self._src[cur:cur+length] )
cur += length
else:
ret.append( self._src[cur:] )
return ret
alist, blist, clist, dlist = splitUp("ABCDEFGHIJ").slice((1,1,3,None))
print alist, blist, clist, dlist
Now, that's readable!
