You can map a and b to operator.or_:
from operator import or_
output = map(or_, a, b)
output becomes:
[0, 1, 1, 1]

output = map(lambda x, y: bool(x or y), a, b)

note that or or the binary operator | could be used here:
a = [0,0,1,1]
b = [0,1,0,1]
a_or_b = [aa | bb for aa, bb in zip(a, b)]
# this also works:
# a_or_b = [aa or bb for aa, bb in zip(a, b)]
print(a_or_b) # [0, 1, 1, 1]

You can use the 'numpy' library and take the maximum over the corresponding axis:
import numpy as np
a = np.array([[0,0,1,1], [0,1,0,1]])
np.amax(a, axis=0)
