您可以做的另一件事是，如果脚本不是以root身份执行的，则脚本会自动调用sudo：
import osimport syseuid = os.geteuid()if euid != 0: print "script not started as root. Running sudo.." args = ['sudo', sys.executable] + sys.argv + [os.environ] # the next line replaces the currently-running process with the sudo os.execlpe('sudo', *args)print 'Running. Your euid is', euid输出：
script not started as root. Running sudo..[sudo] password for bob:Running. Your euid is 0
使用
sudo -k进行测试，以清除所以下一次运行该脚本时它会再次需要密码，你的sudo时间戳。
