1. Backslash is an escape character in Python strings (e.g. "\n" =
newline). You should therefore double-up on your backslashes. (Your
exact string just so happens to work due to a misfeature regarding how
invalid backslash escapes are handled.)
2. Glob/wildcard ("*") expansion is done by the shell, but
subprocess.Popen does not use the shell by default (for good reason!).
Use the `glob` library to do the expansion yourself, in Python:
