Automatically? It sounds like an I/O buffer, in the sense that a block buffered output stream does a write on buffer full. Something like this: class Chunkifier: def __init__(self, size, process): self.size = size self.buffer = [] def append(self, item): self.buffer.append(item) if len(self.buffer) >= self.size: process(sorted(self.buffer)) self.buffer = [] def extend(self, items): for item in items: self.append(item) def burp(items): for item in items: print item burper = Chunkifier(10, burp) burper.extend( (9,8,7,6,5,4,3,2,1,2,3,4,5,6,7,8,9,8,7,6,5,4,3,2,1) ) Totally untested, buyer beware, worth what you paid for it, etc...

In order that there may be no doubt as to which is the top and which is the bottom, for storage purposes it will be seen that the bottom of each head has been labelled with the word TOP. - Instructions for storing British nuclear warheads -- https://mail.python.org/mailman/listinfo/python-list
