using just the Python ≥ 3.9 distribution:

. Clone or download the https://github.com/fluentpython/example-code-2e[_Fluent Python 2e_ code repository] (this repo!).
. Open your shell and go to the _20-futures/getflags/_ directory of your local copy of the repository (this directory!)
. Unzip the _flags.zip_ file, creating a _flags_ directory at _20-futures/getflags/flags/_.
. Open a second shell, go to the _20-futures/getflags/_ directory and run `python3 -m http.server`. This will start a `ThreadingHTTPServer` listening to port 8000, serving the local files. If you open the URL http://localhost:8000/flags/[http://localhost:8000/flags/] with your browser, you'll see a long list of directories named with two-letter country codes from `ad/` to `zw/`.

. Now you can go back to the first shell and run the _flags2*.py_ examples with the default `--server LOCAL` option.
. To test with the `--server DELAY` option, go to _20-futures/getflags/_ and run `python3 slow_server.py`. This binds to port 8001 by default. It will add a random delay of .5s to 5s before each response.
. To test with the `--server ERROR` option, go to _20-futures/getflags/_ and run `python3 slow_server.py 8002 --error-rate .25`.
. To test with the `--server DELAY` option, go to _20-executors/getflags/_ and run `python3 slow_server.py`. This binds to port 8001 by default. It will add a random delay of .5s to 5s before each response.
. To test with the `--server ERROR` option, go to _20-executors/getflags/_ and run `python3 slow_server.py 8002 --error-rate .25`.
Each request will have a 25% probability of getting a

and all responses will be delayed .5s.
