Fix Python – When should I use uuid.uuid1() vs. uuid.uuid4() in python?

I understand the differences between the two from the docs.
Generate a UUID from a host ID, sequence number, and the current time
Generate a random UUID.
So uuid1 uses machine/sequence/time info to generate a UUID. What are the pros and cons of using each?
I know uuid1() can have privacy concerns, since it’s based off of machine….
