2009/5/5 Ricardo Aráoz ricar...@gmail.com:
This seems to work for any length tuples :
a = [(1,2), (3,4, 'goes'), (5,None), (6,7, 8, 'as', None), (8, None),
(9, 0)]
[tup for tup in a if not [e for e in tup if e == None]]
[(1, 2), (3, 4, 'goes'), (9, 0)]
Why that extra for? KISS
a =
ls = [(1,2), (3,4), (5, None), (6,7), (8, None)]
[(x,y) for (x,y) in ls if y]
[(1, 2), (3, 4), (6, 7)]

Nope. That filters out 0 as well as None. Not what the OP asked for.

Nope. That filters out 0 as well as None.
This isn't list comprehension, but it's something to keep in mind:
b = filter(lambda x: None not in x, input_list)
