Generate a version 2 UUID.
The function `uuid_generate` in the Python library uuid is an implementation of RFC 4122's UUID specification. It can generate version 3, 4 or 5 UUIDs and provides methods for setting random bits.

```python
from uuid import uuid4, uuid5
import time
print(uuid4()) # prints '00000000-0000-4000-8000-0000000000037' 
print(uuid4().version)  # Version 4 UUID (not supported by Open Assistant yet!)
print(uuid5())         # prints '11111111-2222-3333-4444-5555555555580'
time.sleep(2)         # Sleep for two seconds before printing next ID
print(uuid5())        # prints '11111111-2222-3333-4444-555555555558f8'
