This part use ls with -t option, so we can't use echo.
I don't know alternate command which is usable on macOS / Linux.
(As far as I know, find and stat can't use the same option on macOS / Linux)

latest=$(python3 -c '
import glob, os
files = glob.glob("dist/pyarrow*.whl")
if files:
    print(max(files, key=os.path.getmtime))
')
echo "$latest"
