Ooh, I wasn't aware of this, but I recently wrote something conceptually similar (albeit slightly lower-level - it's more of a "macro assembler with python syntax"): https://github.com/DavidBuchanan314/p65a https://github.com/DavidBuchanan314/p65a It needs a bit of a refactor, and there aren't any docs except for my example code (which is a serial bootloader, complete with crc checks, for my SBC) Looking closer at OP, it uses AST introspection to do its magic, whereas mine just uses operator overload hacks.
