Hey i would like to contriubute to this issue, can you send me more details regarding the issue, and help me a bit to initiate with the issue ?

@glitchxxx0 Hi! RustPython codebase is changed a lot since #4609 is written.

Linux machine is recommended to run tests.

1. Remove @unittest.expectedFailure from the test https://github.com/RustPython/RustPython/blob/main/Lib/test/test_types.py#L424-L425
2. rustpython-format is now placed in different repository. This task will be multi-repository tasks. The relocated source code is here: https://github.com/RustPython/Parser/blob/main/format/src/format.rs
3. FormatSpec::format_int have to take locale information from somewhere out of the format, which can be used for n format. Because FormatSpec or rustpython-format is not expected to know about platform-specific locale handling, there must be.. something to do it.

Because many things are changed, I don't think this is a good first issue anymore.

Since everybody has different view for problems, sharing everything about the issue is not easy. Please share me any blocking issues what makes you stuck or not to dive in coding. I'll try to catch what's missing for you.

Thank you for visiting!
