How to get the user login/logoff time by Python fo

问题:

I am trying to develop a script or tool to tell about how long each user occupies the computer, in order to manage and balance the resource. As for the user name, Python provides clean way to get it by os.getlogin(). However, I searched and could not find a neat Python API method to get the login and logoff time of that specific user. For Windows, I have to "query user" and this does not work for windows XP. And for Linux, I have to admit I am not good at it. Do you guys know a cross-platform and Python API way to do that?.

Thanks a lot! Di

Windows Solution (should work on xp)

>>> import win32net,time
>>> users,nusers,_ = win32net.NetUserEnum(None,2)
>>> for user in users:
...    print "%-20s %s"%(user['name'],time.ctime(user['last_logon']))
...

you can use

import platform
platform.uname() 

to determine which OS you are in and use a separate method for each OS, for example

import platform
os_name = platform.uname()[0].lower()
if os_name == "windows":
   get_win_login_time()
elif os_name.endswith("nix"):
   get_nix_login_time()
....

to answer your question re network users

import win32net, win32netcon, platform

win32net.NetUserEnum(win32net.NetGetDCName(),2,win32netcon.FILTER_NORMAL_ACCOUNT)
