If you pass the shell command in as a list of strings, it doesn't
actually get executed in a shell, so the wildcards are not expanded.

You probably want:

["sh", "-c", "ls", "../f*"]

 - or -

"ls ../f*".

Beware that if you need to pass special characters like quotes or
backslashes, the shell (plus Python's quoting rules) can make this
very difficult (especially if you use the second form).
