Re: Running another python interpreter

This is very nearly perfect. I have a second console window. 
Unfortunately, the first is waiting for the second to close. Is there 
anyway to specify the equivalent of os.P_NOWAIT?

 Use the subprocess module, passing CREATE_NEW_CONSOLE into creationflags:

 subprocess.call([sys.executable, gateway.py, other, arguments],
  creationflags = subprocess.CREATE_NEW_CONSOLE)

Use the more generic version:

subprocess.Popen([sys.executable, gateway.py, other, arguments],  
creationflags = subprocess.CREATE_NEW_CONSOLE)

For more info on the subprocess module, see

Running another python interpreter

2007-10-18 Thread Simon Pickles 
Hello,

I have several servers which link to each other (and of course, to clients).

At present, I am starting them in turn manually. Is there a way with 
python to say, open gateway.py in a new interpreter window?

I looked at execv, etc, but they seem to replace the current process. 
Ah, maybe I need spawnv().

I am on windows i386, python 2.5

Thanks

Well, I tried:
   
os.spawnv(os.P_NOWAIT, gateway.py, ())

and got:

OSError: [Errno 8] Exec format

Does gateway.py has the python interpreter in the top (i.e., 
#!/usr/local/bin/python)

The OP said he's on Windows so that doesn't matter.

Try with:

os.spawnl(os.P_NOWAIT, sys.executable, sys.executable, gateway.py)

or use the subprocess module.
