How to generate a UUID in Python
Python is a popular programming language that lets you work quickly and integrate systems more effectively. Python is a versatile language and can be used for a wide range of tasks. Some common uses of Python include web development, GUI development, scientific and numeric computing, software development, and system administration.
This is simple Python program that generates a UUID:
- import uuid
- guid = uuid.uuid4()
This program uses the uuid module to generate a random GUID using the uuid4() function. The generated GUID is then printed to the console. The uuid module is part of the Python Standard Library, so you don’t need to install anything to use it.
- Line #1 imports the uuid module from the Python Standard Library. This module provides functions for generating GUIDs.
- Line #2 calls the uuid4() function from the uuid module to generate a random GUID. The generated GUID is then stored in the guid variable.
- Line #3 prints the value of the guid variable to the console. Since the guid variable contains the generated GUID, this will print the GUID to the console.
How to convert from a string to UUID in Python
This program uses the uuid module to convert a string representation of a UUID to a UUID object using the UUID() function. The UUID object is then printed to the console.
- import uuid
- uuid_string = '449947c4-7106-45da-be62-d76c13d141b3'
- uuid_object = uuid.UUID(uuid_string)
- Line #1 imports the uuid module from the Python Standard Library. This module provides functions for working with UUIDs.
- Line #2 defines a string variable named uuid_string and assigns it a value that represents a UUID. This value is a string in the standard UUID format.
- Line #3 calls the UUID() function from the uuid module and passes it the uuid_string variable as an argument. The UUID() function converts the string representation of the UUID to a UUID object and returns it. The returned UUID object is then stored in the uuid_object variable.
- Line #4 prints the value of the uuid_object variable to the console. Since the uuid_object variable contains a UUID object, this will print the UUID to the console.
