Python Time-Ordered UUID

Why?

OrderedUUID

ordereduuid

Generates UUIDs ordered by time generated. The default constructor generates a UUID using a random multicast MAC address as the node: >>> from ordereduuid import OrderedUUID >>> OrderedUUID() OrderedUUID('1ea96141-1da3-c3ef-e978-ab415e52aca4') If a private MAC is not preferred, use the set the private_mac keyword argument to False: >>> OrderedUUID(private_mac=False) OrderedUUID('1ea961a5-25a5-c3bf-e26f-ffffffffffff') REQUIRES TESTING/REVIEW -- UUIDs generated are designed to be used as keys in databases.

사용

import timeflake

# Create a random Timeflake
flake = timeflake.random()
>>> Timeflake(base62='00mx79Rjxvfgr8qat2CeQDs')

# Get the base62, int, hex or bytes representation
flake.base62
>>> '00mx79Rjxvfgr8qat2CeQDs'

flake.hex
>>> '016fa936bff0997a0a3c428548fee8c9'

flake.int
>>> 1909005012028578488143182045514754249

flake.bytes
>>> b'\x01o\xa96\xbf\xf0\x99z\n<B\x85H\xfe\xe8\xc9'

# Convert to the standard library's UUID type
flake.uuid
>>> UUID('016fa936-bff0-997a-0a3c-428548fee8c9')
