Are there builtin functions for elementwise boolean operators over boolean lists?
There is not a built-in way to do this. Generally speaking, list comprehensions and the like are how you do elementwise operations in Python.
Numpy does provide this (using &, for technical limitations) in its array type. Numpy arrays usually perform operations elementwise.
Try:
[ x&y for (x,y) in zip(list_a, list_b)]
The numpy.all function does what you want, if you specify the dimension to collapse on:
>>> all([[True, False, True, False, True], [True, True, False, False, True], [True, True, False, False, True]], 0)array([ True, False, False, False, True], dtype=bool)
