uuid.uuid1() returns pretty similar results

Question

I've generated uuid's by uuid.uuid1() in Python and they all look pretty similar. Why is that? How to randomize them?

UUIDs are designed to be *unique* and not *as different from each other as possible*. — Klaus D., Jan 25 '17 at 07:19

@KlausD., are they similar? why are they similar? they aren't similar. — Torito, Jan 25 '17 at 08:34
The "why?" is explained below. The other two parts of your comment are a matter of perspective. For the requirement of uniqueness a one bit difference is enough. — Klaus D., Jan 25 '17 at 08:38

That is because the uuid1 is generated from your machine ID and time stamp and the machine ID in your case remains constant, that's why they look pretty similar at the end. You may use uuid4() to get a random unique uuid.
