Summary of Changes
Hello @ShaharNaveh, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request introduces a new command-line interface for the uuid module, significantly enhancing its usability for quick UUID generation. It also improves the flexibility of uuid3 and uuid5 by allowing bytes input for names. Concurrently, the PR refines internal platform detection, removes deprecated code, and strengthens the module's overall robustness and test coverage.
Highlights
- New Command-Line Interface (CLI): The
uuidmodule now includes a command-line interface via itsmain()function, allowing users to generate UUIDs of different versions (1, 3, 4, 5) directly from the terminal. It supports specifying namespaces and names for version 3 and 5 UUIDs. - Enhanced
uuid3anduuid5Functionality: Theuuid3anduuid5functions now explicitly supportbytesobjects as input for thenameargument, in addition to strings. This provides more flexibility for users working with binary data. - Internal Code Refinements and Deprecations: Several internal improvements have been made, including refined platform detection logic (e.g., for Linux and Android), removal of deprecated internal functions (
_ipconfig_getnode,_netbios_getnode,_load_system_functions), and more robust exception handling for module imports and command execution. - Test Suite Expansion: The test suite (
test_uuid.py) has been significantly expanded to cover the new CLI functionality, the acceptance ofbytesinput foruuid3anduuid5, and to reflect changes in internal logic and deprecations.

Code Review
This pull request updates the uuid module, introducing several improvements. Key changes include fixing uuid3 and uuid5 to correctly handle bytes type names, adding a command-line interface for generating UUIDs, and various code cleanups like removing deprecated functions and improving platform detection. The test suite has been expanded to cover the new CLI and the bytes handling in uuid3/uuid5.
My review focuses on improving maintainability in the tests by reducing code duplication and enhancing the robustness of the new command-line interface by adding error handling for invalid user input.

If a user provides an invalid UUID string for the namespace, the UUID(namespace) constructor will raise a ValueError. This exception is currently unhandled and will cause a traceback, which is not ideal for a command-line tool. For a better user experience, please catch this exception and print a user-friendly error message, for example by using parser.error().

This test block for byte objects is very similar to the one for string objects that follows. To improve maintainability and reduce code duplication, consider refactoring these tests. You could define the test cases (namespace, name, expected UUID) in a single data structure and then iterate through it, running the assertions for both byte and string versions of the name within the same loop, perhaps using subTest to distinguish them.

Similar to test_uuid3, this test block for byte objects is nearly identical to the one for string objects. To avoid code duplication, I recommend refactoring. A single set of test data could be used, and you can loop over it to test both byte and string inputs, which would make the test more concise and easier to maintain.

@gemini-code-assist You shouldn't review any code under Lib/. Could you please make a PR to ignore those files?

Thanks for pointing that out! I'll be sure to exclude Lib/ from future reviews. I appreciate the feedback.

Don't you have any configuration file? How can I check the list of excluded path?
