Recursively yield every file under a directory matching a predicate. Built on pathlib.rglob; the predicate gives you precise control without listing the whole tree up front.
Python

root: str | Path,
predicate: Callable[[Path], bool] = lambda _: True,
) -> Iterator[Path]:
for p in Path(root).rglob("*"):
if p.is_file() and predicate(p):
yield p
# Every .py file under src/
for path in walk_files("src", lambda p: p.suffix == ".py"):
print(path)
# All files modified in the last 24 hours
