Why that extra "for"? KISS
>>> a = [(1,2

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

This isn't list comprehension, but it's something to keep in mind:
b = filter(lambda x: None not in x, input_list)

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
12 matches
