I have a list like this:
A = [[1,2,3,4],[1,1,2,4],[1,2,3,False],[1,False,2,3],[1,2,3,4],[1,2,3,'word'],[5,6,7,8],[1,4,3,4],[True,1,2,4],[0,1,0,1],[0,0,0,0],[False,False,False,False]]
and I want as output a list like this:
A = [[1,2,3,4],[1,1,2,4],[1,2,3,4],[5,6,7,8],[1,4,3,4],[0,1,0,1],[0,0,0,0]]
I just want to delete or remove a any list. it have member of string or logical.

We can do this with list comprehension where we perform a filter with any(..) that checks if there is any element that is an instance of str or bool:
[sublist for sublist in A if not any(isinstance(e, (str, bool)) for e in sublist)]
this then yields:
>>> [sublist for sublist in A if not any(isinstance(e, (str, bool)) for e in sublist)]
[[1, 2, 3, 4], [1, 1, 2, 4], [1, 2, 3, 4], [5, 6, 7, 8], [1, 4, 3, 4], [0, 1, 0, 1], [0, 0, 0, 0]]

@lyca: the element in the generator, it enumerates oversublistwith... for e in sublist.
