How can I generate a unique ID in Python? [duplicate]
You might want Python's UUID functions:
21.15. uuid — UUID objects according to RFC 4122
eg:
import uuidprint uuid.uuid4()7d529dd4-548b-4258-aa8e-23e34dc8d43d
unique and random are mutually exclusive. perhaps you want this?
import randomdef uniqueid(): seed = random.getrandbits(32) while True: yield seed seed += 1Usage:
unique_sequence = uniqueid()id1 = next(unique_sequence)id2 = next(unique_sequence)id3 = next(unique_sequence)ids = list(itertools.islice(unique_sequence, 1000))no two returned id is the same (Unique) and this is based on a randomized seed value
