To make it crystal clear, the above was to illustrate the algorithm used in Python 2, not a suggestion. Python 2 uses that "useless testing" -- which is cheap compared to actual I/O. > The following is clearer > > # ------------------------- > n=5 > for i in range(n-1): > print(i, end=' ') > print(n-1) > # ------------------------- > > > but doesn't solve all the cases (imagine a string or an iterator). I still think you should live with a trailing space or go with my actual suggestion print(*range(5)) -- http://mail.python.org/mailman/listinfo/python-list
