subprocess.call error

Hey guys....

I use Python 2.6.2. I recently created a program which accepts commands from my website, here's the code I used:

import urllib
import subprocess
import time

open_site=urllib.urlopen("http://www.sravan953.webs.com/command_python.htm")
read_site=open_site.read()

def run_program():
    current=time.asctime()
    print 'Runnning program'+' ['+current+']'
    subprocess.call(read_site)

def check_argument():
    current=time.asctime()
    if read_site=='':
        print 'No command given'+' ['+current+']'
        timer()
    else:
        print 'Command found...'+' ['+current+']'
        run_program()

def timer():
    current=time.asctime()
    print 'Checking for commands...'+' ['+current+']'
    time.sleep(2)
    check_argument()

timer()

But when I run it I get an error:

Traceback (most recent call last):
File "C:\Documents and Settings\Sravan\My Documents\Sravan\PYTHON\Accepshun.py", line 28, in <module>

errread, errwrite)
File "C:\Python26\lib\subprocess.py", line 804, in _execute_child
startupinfo)
WindowsError: [Error 2] The system cannot find the file specified

I only recently uninstalled Python 2.6.2 and re-installed it again, and then installed py2exe....it used to work fine before I uninstalled it, is there anything else I have to install?

Thanks for the help guys...

subprocess.call(["program-name", "arg1", "arg2"]) takes an executable program with arguments.

You are giving it an html script code. That won't work!

Yeah but, I have made sure that in the webpage, there is only text and no HTML tags...so basically it should work right?

Run this little test code, it's the beginning of your program ...

import urllib

url = "http://www.sravan953.webs.com/command_python.htm"
open_site = urllib.urlopen(url)
read_site = open_site.read()

print(read_site)

The only thing you can execute this result with is a web browser.
You can run the url directly using the Python module webbrowser ...

import webbrowser

url = "http://www.sravan953.webs.com/command_python.htm"
webbrowser.open(url)
