Use, instead, the DSU that is now build into Python: listofsets.sort(key=len) this will be faster (as well as more readable &c) than programming your own DSU, and is exactly the reason the key= parameter was added. I also suggest avoiding reduce in favor of a simple explicit loop. Alex -- http://mail.python.org/mailman/listinfo/python-list
