how to make binary to bit 8 in python

Question

i have variable contains with binary with type int ([101, 1101, 11001]) but i want to xor it with another variable, so i must change to string and add "0" so it has 8 number example 101 it'll become 00000101

i was trying change int to str but it cannot works. here's my code:

def bit8(input):
    print(input)
    y = str(input)
    print(y)

    index = 0

    for index, a in enumerate(y):
        y[index] = a + "0"

    return y[index]

input will contains with array [101, 1101, 11001] and it will become ["00000101", "00001101", "00011001"] the idea is i will split them and i will add "0" and save it again to new array

but i don't know how exactly to do it. please help me

You can simply try format

l =[101, 1101, 11001]

c = "{:08d}".format
print([c(item) for item in l])

output #

['00000101', '00001101', '00011001']

As a function

def bit8(input):
    c = "{:08d}".format
    ou=([c(item) for item in input])

    return ou

Driver code

print(bit8(l))

zfill also works

l =[101, 1101, 11001]


def bit8(input):
    ou2=[str(i).zfill(8) for i in input]
    return ou2

Driver code #

print(bit8(l))

output for zfill method #

['00000101', '00001101', '00011001']
