Here's an example for integers on a 64-bit machine: >>> g = ((x*(2**64 - 1), hash(x*(2**64 - 1))) for x in xrange(1, 1000000)) >>> d = dict(g) This takes ages to complete and only uses very little memory. The input data has some 32MB if written down in decimal numbers - not all that much data either. 32397634 ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue13703> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
