Convert list of integer arrays to a list of string arrays

Question

I'm attempting to convert an int array :

[array([0, 0, 0, 0, 0, 0, 1, 1, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 1, 0, 1, 1,
        0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 1, 1, 1, 1, 0, 1, 1, 0, 0,
        1, 0, 1, 1, 1, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0,
        0, 0, 1, 0, 1, 0, 1, 1, 0, 0, 1, 0, 1, 0, 1, 1, 1, 0, 1, 0, 1, 0, 0,
        0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0, 1, 1, 0, 1, 1, 1, 0, 1, 1, 1, 0,
        0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 1, 0, 0, 1, 0, 0, 0, 0, 0, 0,
        0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 1, 1, 1, 0, 0, 1, 1, 0,
        1, 1, 0, 1, 1, 1, 0, 1, 1, 1, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0,
        0, 1, 0, 1, 1, 1, 1, 0, 1, 0, 0, 0, 1, 1, 0, 1, 1, 0, 1, 0, 0, 0, 0,

        0, 0, 0, 0, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
        0, 0, 0, 0, 0, 0]),
 array([0, 0, 0, 1, 1, 0, 0, 0, 0, 0, 0, 1, 0, 1, 0, 0, 0, 1, 0, 1, 0, 0, 0,
        0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 1, 0, 1, 0, 0, 1, 0, 0, 0,
        1, 0, 0, 0, 1, 0, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0,
        0, 0, 1, 0, 1, 0, 1, 1, 0, 1, 1, 1, 1, 0, 1, 1, 1, 0, 1, 1, 0, 1, 1,
        0, 0, 1, 1, 1, 0, 0, 1, 1, 1, 1, 0, 0, 1, 0, 1, 1, 1, 0, 1, 1, 1, 0,
        0, 0, 0, 0, 0, 0, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 1,
        0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 1, 0, 1, 0, 0, 1, 0, 0,
        0, 1, 1, 0, 0, 1, 0, 1, 1, 1, 0, 0, 0, 0, 1, 0, 1, 0, 0, 0, 0, 0, 0,

        0, 0, 0, 0, 0, 0])]

to string array :

[array(["0 0 0 0 0 0 1 1 1 0 0 0 0 1 0 0 0 0 1 1 0 1 1
        0 0 0 0 0 0 0 0 0 0 0 0 1 0 1 1 1 1 0 1 1 0 0

 array(["0 0 0 1 1 0 0 0 0 0 0 1 0 1 0 0 0 1 0 1 0 0 0

Here is code I'm trying :

mapped = map(lambda x: str(x), oneHotEncodedX)
list(mapped)

But this insert's new line characters and quotes are surrounded by [ ] :

['[0 0 0 0 0 0 1 1 1 0 0 0 0 1 0 0 0 0 1 1 0 1 1 0 0 0 0 0 0 0 0 0 0 0 0 1 0\n 1 1 1 1 0 1 1 0 0 1 0 1 1 1 0 1 1 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 1 0 1\n 0 1 1 0 0 1 0 1 0 1 1 1 0 1 0 1 0 0 0 0 1 1 1 1 1 1 1 1 1 0 1 1 0 1 1 1 0\n 1 1 1 0 0 0 0 0 0 0 0 0 0 0 0 1 0 1 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0\n 0 0 0 1 0 1 1 1 0 0 1 1 0 1 1 0 1 1 1 0 1 1 1 0 0 0 0 0 0 1 0 0 0 0 0 0 0\n 1 0 1 1 1 1 0 1 0 0 0 1 1 0 1 1 0 1 0 0 0 0 0 0 0 0 1 0 0 0 0 1 0 0 0 0 0\n 0 0 0 0 0 0 0 1 0 0 0 0 0 1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0]',

How to convert to array of strings where each strings where each string contains sub array elements ?

are you dealing with numpy arrays? it's worth to add the appropriate tag in that case — RomanPerekhrest

use this as reference a = [0,1, 1, 2,2,3 ] than print([" ".join(map(str, a))]) — Vaibhav

I believe you could use:

out = list(map(lambda x: np.array(' '.join(x.astype(str))), oneHotEncodedX))

print(out)
[array('0 0 0 0 0 0 1 1 1 0 0 0 0 1 0 0 0 0 1 1 0 1 1 0 0 0 0 0 0 0 0 0 0 0 0 1 0 1 1 1 1 0 1 1 0 0 1 0 1 1 1 0 1 1 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 1 0 1 0 1 1 0 0 1 0 1 0 1 1 1 0 1 0 1 0 0 0 0 1 1 1 1 1 1 1 1 1 0 1 1 0 1 1 1 0 1 1 1 0 0 0 0 0 0 0 0 0 0 0 0 1 0 1 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 0 1 1 1 0 0 1 1 0 1 1 0 1 1 1 0 1 1 1 0 0 0 0 0 0 1 0 0 0 0 0 0 0 1 0 1 1 1 1 0 1 0 0 0 1 1 0 1 1 0 1 0 0 0 0 0 0 0 0 1 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0',
