Just start the server using:

    python -m http.server 8000

to share a directory over a local network. Then you can point a web browser on another device to port 8000 of the server's IP address to download files. However, this can be slow for larger files.

A friend wrote a faster and more sophisticated version of `python -m http.server 8000` in rust which also supports uploads, you can read about here: https://news.ycombinator.com/item?id=37628347
