Restart your python program.

This snippet defines a function restart_program() which restarts your python program from within your python program.

import sys
import os

def restart_program():
    """Restarts the current program.
    Note: this function does not return. Any cleanup action (like
    saving data) must be done before calling this function."""
    python = sys.executable
    os.execl(python, python, * sys.argv)

if __name__ == "__main__":
    answer = raw_input("Do you want to restart this program ? ")
    if answer.strip() in "y Y yes Yes YES".split():
        restart_program()

This code is not working on my version of Python (3.2). It just restarts the shell and does not do anything else.

If you are using this in Idle, it won't work because the python process running in the shell is different from Idle gui's process. This will only restart the process running in the shell, not Idle itself.

It is not working in either the shell or Idle. It's strange because when I was running the program on another computer (which I suppose must use a different version of Python) it worked completely fine.

What do you exactly mean by 'the shell' ? also what's your OS ?

i.e. I double-click the .py file to execute it. It works in both the shell and IDLE in the version which I use at home (Python 3.1.2 on Windows Vista) but neither in the version I use at school (Python 3.2 on Windows 7).

Is that 3.2 3.2.2 as there was an issue with input statement with 3.2.1? Probably not reason though, at that problem would make program OK in IDLE and not OK in direct excecution.

Sorry about this, it turns out it was just my account... which is a bit bizarre but it seems to be working fine for others.
