Whats more random, hashlib or urandom?

Question

I\'m working on a project with a friend where we need to generate a random hash. Before we had time to discuss, we both came up with different approaches and because they are us

Answer 1

This solution:

os.urandom(16).encode('hex')

is the best since it uses the OS to generate randomness which should be usable for cryptographic purposes (depends on the OS implementation).

random.random() generates pseudo-random values.

Hashing a random value does not add any new randomness.
