A hyphen symbol separates each component. Output: Printing my First UUID of version 1Ī9e86162-d472-11e8-b36c-ccaf789d94a0 Structure of UUIDĪs you can see in the output UUID is made up of five components, and each component has a fixed length. Print ("Printing my First UUID of version 1") # make a UUID based on the host address and current time Now, Let see the simple example to get the universally unique Id.

UUID4 uses pseudo-random number generators to generate UUID.

UUID 3 uses MD5 hashing, and UUID 5 uses SHA-1 hashing.

UUID3 and UUID 5 uses cryptographic hashing and application-provided text strings to generate UUID.

This version uses the IEEE 802 MAC addresses. UUID1 – Generate UUID using a Host MAC address, sequence number and the current time.Python UUID module supports the following versions of UUIDs. UUID generated using this module is immutable. Hence using Python UUID module, you can generate versions 1, 3, 4, and 5 UUIDs. RFC 4122 document specifies three algorithms to generate UUIDs. RFC 4122 specification includes all the details and algorithms to generate the Unique Identifiers of all the versions. RFC 4122 is a standard and Copyright (C) of The Internet Society. Python UUID module implemented as per RFC 4122. Therefore UUID is useful where a unique value is necessary.ĭo you want to learn more about what is UUID? then refer to this Wikipedia Link.when we talk about space and time means when UUID generated according to the standard then the identifier does not duplicate one that has already been created or will be created to identify something else. UUID can guarantee the uniqueness of Identifiers across space and time.However, What is it? Let’s understand this in brief.Ī UUID is 128 bits long number or ID to uniquely identify the documents, Users, resources or information in computer systems. You can also call it as GUID, i.e., Globally Unique Identifier.
