I noticed this today, using Python2.7 or 3.4, and wondered if it is implementation dependent:
You can use 'extend' to add set elements to a list and use 'update' to add list elements to a set. >>> m = ['one', 'two'] >>> p = set(['three', 'four']) >>> m.extend(p) >>> m ['one', 'two', 'four', 'three'] >>> m = ['one', 'two'] >>> p = set(['three', 'four']) >>> p.update(m) >>> p set(['four', 'three', 'two', 'one']) Useful if you don't care about ordering. Not sure if it's dangerous. thanks, --Tim -- https://mail.python.org/mailman/listinfo/python-list
