Rus Python script interactively

[Gnarlodious]

In an interactive session (I am using iPython), what is the most
elegant way to run a Python script from Terminal? Right now I am
saying:

import subprocess
subprocess.call("python /path/to/scriptname.py", shell=True)

But I am calling a shell process and I'd rather not. The script just
runs, no inputs are needed. Is there a more Pythonesque method?
