You are misunderstanding something that is fundamental in Python, namely that anything that is done inplace *ALWAYS* returns None as a warning that the operation has been done inplace, so you're never going to get anything back.  All you need do is change your original code as follows:-

from random import shuffle

a = [1,2,3,4,5]
shuffle(a)
b = a[:3]
print(b)
