map(filterOut2, data) works:

>>> data = [[1,2,3,5],[1,2,5,2],[3,5,2,8],[6,3,1,2],[5,3,2,5],[4,1,2,5] ]
... def filterOut2(line):
...     return [x for x in line if x != 2]
... list(map(filterOut2, data))
...
[[1, 3, 5], [1, 5], [3, 5, 8], [6, 3, 1], [5, 3, 5], [4, 1, 5]]

map() takes exactly 1 argument (2 given)

Looks like you redefined map. Try __builtin__.map(filterOut2, data).

Or, use a list comprehension:

>>> [filterOut2(line) for line in data]
[[1, 3, 5], [1, 5], [3, 5, 8], [6, 3, 1], [5, 3, 5], [4, 1, 5]]
