Additionally, using a UUID reduces the chances of future ID issues and eases the development of the architecture of any technology much easier. No other ID can be found similar to a UUID. It cannot be the same and is not irreplaceable as well. Moreover, if the website is a social media platform, then each post or update will also contain a unique ID of its own.īut a UUID is a special ID that uniquely identifies a record in the database universally. For instance, a web user will have a unique ID of their own. When talking about back-end development, an ID is simply a unique identifier for a data record. Use the UUID which was created in the given module and print it out to see the output.Creates a UUID based on a namespace and a name using the function uuid.uuid5(namespace, name).Creates a random UUID using uuid.uuid4().The function uuid.uuid1() creates a UUID by utilizing the computer's MAC address and the current time.Use one of the functions in the uuid module to generate a UUID. Let’s look at the steps to generate the same: To generate a UUID in python, one can use the ‘uuid’ module that comes with a standard library. UUID Python generator module is implemented in accordance with RFC 4122, which includes all of the data and algorithms needed to produce all versions of the UUID. This is because these are generated using a combination of time, machine information, and some random data. Is UUID really unique? The chances of generating two identical UUIDs in Python are extremely low, making it highly unlikely that two different entities will have the same UUID. The module has a UUID class used to generate UUIDs of different versions: versions 1, 3, 4, and 5. Is UUID inbuilt into Python? Yes, UUID is an inbuilt module and doesn't require any third-party libraries for installation. The UUID module offers the ability to produce distinctive IDs in accordance with the RFC 4122 definition. In Python, UUID is a 128-character string of alphanumeric variable type, that uniquely identifies an object, entity, or resource in both space and time of a table. UUID stands for Universally Unique Identifier. With the help of a special identifier, identifying a field would be much more simpler and convenient. This is where a unique identifier comes into play. Here, multiple fields like name, address, etc cannot be used as a unique identifier because two people can have the same name, same address, and more. Generally, when coders work with a certain database, it’s a standard procedure to employ a sort of unique ID field that can provide each row of a table, with a special kind of identifier.įor example, consider a database for customers. Let's learn how to generate UUID with an example, its various functions, and its advantages. When dealing with data, we use UUID in Python for making random IDs to easily identify a field.
