in python, the uuid module provides a way to generate universally unique identifiers, commonly known as uuids. uuids are useful in scenarios where unique identifiers are needed, such as in distributed systems or when creating unique filenames. in this tutorial, we'll explore the uuid module and its various functions with code examples.
a uuid (universally unique identifier) is a 128-bit identifier that is guaranteed to be unique across both time and space. it is typically represented as a string of 32 hexadecimal characters, grouped into five segments separated by hyphens. uuids are commonly used in scenarios where uniqueness is crucial, such as in distributed systems, databases, and file naming.
the uuid module in python provides functions for generating and working with uuids. let's explore some of the key functions.
to generate a new uuid, you can use the uuid.uuid4() function. this function creates a random uuid.
uuids can be represented in different formats, such as string, bytes, or integer. the str() function is commonly used to obtain the string representation.
if you have a uuid in string format and want to convert it to a uuid object, you can use the uuid.uuid() constructor.
uuid objects have several properties, such as hex, int, and bytes, which provide different representations of the uuid.
let's use uuids to generate unique filenames in a hypothetical scenario.
