I think PyQt is nice enough to accept a Python list here. Also, I don't
think you can use a shell redirection (>) like this, so I'd try:
self.proc.start("lout", ["-o", "my_file.ps", "my_file.lout"])
If you really wanted to use redirection you'd have to do it yourself,
that is:
self.proc.start("lout", ["my_file.lout"])
# Now read the process's stdout and write that to your .ps file.
Off Topic:
In lout (and many other apps) the -o option says write the postscript to
the filename following; do lout -v for a summary of all the options; and
don't use the PDF option, use ghostscript for PDF.
