python uuid4

The uuid4 function in Python is used to generate a random UUID (Universally Unique Identifier) using the RFC 4122 version 4 algorithm.

UUIDs are 128-bit unique identifiers that can be used to identify objects or entities in a distributed system. They are typically represented as a string of 32 hexadecimal digits separated by hyphens, such as "a6a314b3-3f3d-4bbc-8d6c-0c8f8e60f7d0".

To use the uuid4 function in Python, you need to import the uuid module:

import uuid

Then you can generate a random UUID using the uuid4 function:

uuid_value = uuid.uuid4()

This will return a UUID object that you can use to get the UUID string representation:

uuid_string = str(uuid_value)

You can also get the UUID bytes representation:

uuid_bytes = uuid_value.bytes

And you can convert a UUID string back to a UUID object:

uuid_object = uuid.UUID(uuid_string)
