Soon there will be, but currently: no. What you are after is a ternary operator like _?_:_ in C. There have been plenty of discussions about these - search this NG. Depending on your usecase, either if b is not None: a = b else: a = 1 or a = [1,b][b is not None] or even a = b or 1 will do the trick. But PLEASE read the discussions first, to understand the reasons and implications. Diez -- http://mail.python.org/mailman/listinfo/python-list
