os.system, os.spawn, the process module, os.popen[1,2,3,4], this is a
pretty basic thing, not trying to be mean, but you should look in the
python docs, this is definitely in there. Also, the subprocess module
is meant to replace all of those but i haven't looked too closely at it
yet, so the following might not be perfect.

import subprocess as sp
sp.call(['wmplayer.exe', 'some_args_probably_a_movie_name'])

you'll probably need to use the full path for media player, and the
call() function is a simplified command within the subprocess module,
useful if you don't really need to redirect input/output/errors or
other aspects of the opened application. Also, you'll probably want
something more like: retcode = sp.call(...), so that you can check the
return code to see if it was successful. Check out the subprocess
module.

Cheers,
Jordan

Here's another way of doing it:
import os
TheCommandIwantTorun = '"C:\Program\Windows Media Player\wmplayer.
exe"' #saves the command to a string
os.system(TheCommandIwantTorun) #runs TheCommandIwantTorun in the
command prompt (windows)
