Pick random integers from list elements of same index and generate a list

I have two lists a & b and I need to pick a random element of a[i] and b[i] and generate z.

a = [1, 0, 1, 1, 0, 1]
b = [1, 1, 0, 1, 0, 0]

z = [1, 0, 1, 1, 0, 0]

I used the below mentioned code:

import random
z = []
for i in range(6):
    value = random(a[i],b[i])
    z.append(value)
print z

and I get the following error:

TypeError: 'module' object is not callable

First off all you have to import random module.

import random

Then you can call any of its method:

random.random()

Furthermore you have should choose random.choice():

value = random.sample([a[i],b[i]], 1)

You can use random.choice (docs here).

Return a random element from the non-empty sequence seq.

It selects one value from a list of values. For each iteration, you can just create a list of a[i] and b[i].

for i in range(6):
    value = random.choice([a[i],b[i]])
    z.append(value)
print( z)

# [1, 1, 1, 1, 0, 0]

Another option is to use random.sample where k=1 here and [a[i],b[i]] is the population as following

Return a k length list of unique elements chosen from the population sequence or set

value = random.sample([a[i],b[i]], 1)
z.append(value[0])

Here value[0] is used because value is a list containing single element so by using [0] you get that element without the list.

You're calling random as if it's a function, when in fact it's a module. You need to use random.choice to choose one of the two options:

value = random.choice([a[i],b[i]])
