You could use the urllib module to download the file, then use the
subprocess module to spawn the javaws executable and pass it the
location of the jnlp file as a parameter.

https://docs.python.org/3.6/howto/urllib2.html
https://docs.python.org/3.6/library/subprocess.html

There are other ways besides launching javaws directly, such as asking
cmd.exe to invoke "start" and the jnlp file so that the default javaws
executable will run. On Mac there's the "open" binary that can do the
same thing, and on Linux, xdg-open.
