Generates an identifier - a random unique string consisting of letters and numbers. Creates UUID (Universally unique identifier) version 4. It works based on 8 functionsmt_rand()and has the format%04x%04x-%04x-%04x-%04x-%04x%04x%04x%04x- consists of 5 parts: ...
UUID4 uses pseudo-random number generators to generate UUID. Now, Let see the simple example to get the universally unique Id. import uuid # make a UUID based on the host address and current time uuidOne = uuid.uuid1() print ("Printing my First UUID of version 1") ...
UUIDs are generated using a combination of time and space parameters. The time parameter is based on the current time and the unique MAC address of the computer generating the UUID. The space parameter is a random number that is generated using a cryptographic algorithm. ...
