Thanks for your help - I have a greater understanding of what's going

find a proper argument. Unfortunately, I know a bit less about vlc
command line arguments than I do about Python's generation of those
arguments ;)
I had or
Is there a method by which I can get an exact representation of command

argument error I receive shows me an argument that looks exactly like
the argument that I use with Bash (it should - I copied and pasted it) -
but the Bash versi

I am forever confused, however, on which methods can be found where. I
just spent quarter of an hour searching in sys,* os.*, and shutil.*. for

find it more expedient bypass the OS shell and work almost exclusively
with Python?
