Do you really think the python popen() workalike with optional shell inclusion is better than running in a shell? More secure perhaps? Easier to read? I forced a developer from my team who would not stop using subprocess calls (including $SHELL) in random new python scripts with hard coded arguments instead of writing a single shell script that could be reused. subprocess is a tarpit and is more misused than any other python function.
