# Its a bad practice to copy multiple times a str variable that can be changed any time. Lets define it once and reuse later
binaries_path = Path(af_module.__name__) / "binaries"

for path in local_paths:
    # Assuming you applied changes in the comments above, we can avoid extra tabulation by exiting the cycle earlier
    if not lpath.exists():
        continue

    files = [x.name for x in binaries_path.glob("*") if x.is_file()]  # can be simplified 'coz binaries_path is already a path
    # It'd be better to bind lib names with their devices/frameworks because likely adding a new backend, e.g., cuda2 will lead to adding afcuda2 or smth
    query_libnames = [f'af{backend.name}' for backend in BackendType] + ['af', 'forge']  # yup, it will also add afunified, but who cares if it will be skipped 🤷 
    found_lib_in_dir = any(lib_name in files for lib_name in query_libnames)  # lets make it O(n) at least

    if not found_lib_in_dir:  # Same as above to avoid extra tabulation
        continue

        print(f"Found binary file by path: {path / binaries_path}")
    
    return path / binaries_path  # returns Path
 
raise RuntimeError("No binaries were found in site path.")

Yea, and it's better to make descriptive comments if you catch errors or add implicit verbosing
