Is this the right way to run a shell script inside

Question

import subprocess
retcode = subprocess.call(["/home/myuser/go.sh", "abc.txt", "xyz.txt"])

When I run these 2 lines, will I be doing exactly this?:

/home/myuser/go.sh abc.txt xyz.txt

Why do I get this error? But when I run go.sh normally, I don't get that error.

I just got this error on Mac OS, while trying to call a one-line script using subprocess.call. The script ran fine when called from the command line. After adding the shebang line #!/usr/bin/env sh, it also ran fine via subprocess.call.

It appears, while the shell has a default executor for text files marked executable, subprocess.Popen does not.
