timeit 'x=1;(x,x,x)' 0.36 usec per loop timeit 'x=1;[x,x,x]' 0.425 usec per loop Introducing a new opcode BUILD_STRING to inline PyTuple_New + PyUnicode_Join to replace BUILD_TUPLE + CALL_FUNCTION should benchmark against BUILD_TUPLE version, not BUILD_LIST + CALL_FUNCTION ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27078> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
