I'm trying to set up a simple filter using a list comprehension. If I have a list of tuples, a = [(1,2), (3,4), (5,None), (6,7), (8, None)] and I wanted to filter out all tuples containing None, I would like to get the new list b = [(1,2), (3,4),(6,7)].
I tried b = [i for i in a if t for t in i is not None] but I get the error that "t is not defined". What am I doing wrong? -- http://mail.python.org/mailman/listinfo/python-list
