One of my students wrote some code for Python 3, and when I went to test it, I typed 'python scriptname' out of habit (most of my students use Py2)... and it almost perfectly worked. The only part that didn't was a class definition that didn't explicitly subclass object, and then used @property. Just changing that class declaration would have made his code 2/3 compatible - and he didn't put any effort into it at all. He literally made his code *accidentally* (almost-)Py2-compatible. You don't need to be afraid of the gap. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
