In bash, the <(...) notation is like piping: it executes the command inside the parentheses and uses that as standard input to ffmpeg. So if you work out what the commands are doing (it looks like they emit a line saying "file '...'" for each .wav file in the current directory, possibly including subdirectories) and replicate that in Python, you should be able to make it cross-platform.
