play a midi file from the interpreter?

[Elaine Jackson]

(How) can you make it so that a function invoked in the python interpreter can
run another program? (Like the webbrowser module does, only not with a web
browser.) If it matters the OS is Windows98 and the specific aim in mind is to
have a function that saves some data as a midi file and then causes the said
midi file to play.

Use the popen() call in the os module.

Could you sketch me a useage example? I'm finding the documentation extremely
sparse. I've heard of 'pipes', but I don't actually know what they are.

Basically you just pass popen a string that looks like one typed at the
command prompt:

# untested
# (Eg. I don't know the name of your midi file player
# so I call it playmidifile.exe)

import os
midifilename = 'c:/path/to/midifile.mid'
result = os.popen('playmidifile.exe %s' % midifilename)
print result
