It does strong validation and produces correct results. uuid Generate a random UUID randomuuid uuid.uuid4() (randomuuid) uuid Generate a UUID based on the host ID and current time timebaseduuid uuid. UUID.fields which includes fields like time, clockseq, node etc. UUID.hex which includes a 32 -bit hexadecimal string. UUID.int which includes a 128 -bit integer. But for my purposes this function is all I need. There are five attributes that the UUID generator Python module provides as follows: tes which includes a 16 -byte string. PS: The subprocess call could probably be replaced with ctypes directly calling Windows kernel/DLLs. Uses Windows API to get the computer's permanent UUID, then processes the string to ensure it's a valid UUID, and lastly returns a Python object ( ) which gives you convenient ways to use the data (such as 128-bit integer, hex string, etc). # Ensure we have exactly 32 characters (16 bytes). ![]() # and useless dashes etc, by only keeping hex (0-9 A-F) chars. # Remove the surrounding whitespace (newlines, space, etc) # Attempt to extract the UUID from the command's result. Is there another method to generate a unique ID which is shorter in terms of characters EDIT: If ID is usable as primary key then even better Granularity should be better than 1ms This code could be distributed, so we can't assume time independence. Txt = subprocess.check_output("wmic csproduct get uuid").decode() So we can generate a unique id with str (uuid.uuid4 ()), which is 36 characters long. # Ask Windows for the device's permanent UUID. from typing import OptionalÄef get_windows_uuid() -> Optional: If you want to generate GUIDs at scale, just. Use the Copy/Download button to grab them or copy codes manually. uuid5 Generate a UUID from an SHA1 hash of one of the namespaces above and a name. uuid3 Generate a UUID from an MD5 hash of one of the namespaces above and a name. ![]() If you want a permanent UUID that identifies a machine uniquely on Windows, you can use this trick: (Copied from my answer at ). Open our ID Generator tool page The tool itself produces 5 GUIDs for your use. Im using Pythons UUID function to create unique IDs for objects to be stored in a database: > import uuid > print uuid. To generate an RFC 4122 UUID, use one of these functions: uuid1 Generate a UUID from the time and hostname.
