superuser in python

Hi,

I am a newbie in python and I have a question:  How can I run a linux system command as a superuser, using a python script?

Re: superuser in python

Google for "python os system sudo".

or do "sudo ./script.py"

edit: or even better yet, exactly describe what you're trying to do.

Re: superuser in python

Actually I have a basic code:

import os
import sys
from PyQt4.QtCore import *
from PyQt4.QtGui import *
 
def main():
    app = QApplication(sys.argv)
    w = MyWindow()
    w.show()
    sys.exit(app.exec_())
 
class MyWindow(QWidget):
    def __init__(self, *args):
        QWidget.__init__(self, *args)

        self.le = QLineEdit()
        self.te = QTextEdit()
        layout = QVBoxLayout(self)
        layout.addWidget(self.le)
        layout.addWidget(self.te)
        self.setLayout(layout)
        self.connect(self.le, SIGNAL("returnPressed(void)"), self.komut_calistir)

    def komut_calistir(self):
        komut = str(self.le.text())
        cikti = os.popen4(komut)[1].read()
        self.te.setText(cikti)
 
if __name__ == "__main__":
    main()

When I tried "pacman -Syu", got an error:

sudo: no tty present and no askpass program specified

Re: superuser in python

Since you have a GUI, you should use a graphical sudo replacement, like e.g. kdesu, gksu, gtksu, ktsuss, ...
Alternatively you can run sudo in askpass-mode (sudo -A) and set the environment variable SUDO_ASKPASS to a valid SSH_ASKPASS application, e.g. openssh-askpass

1. https://projects.archlinux.org/users/remy/pyalpm.git/
2. *never* use os.(p)open*, use the subprocess module
