Get name of users(persons, not applications) in linux system using psutil library

Question

I am trying to use psutil library to get users logged in to linux system.

For that i used function psutil.users()

>>> import psutil
>>> psutil.users()
[suser(name='vibhcool', terminal='tty2',host='localhost',started=1473815296.0)]

I want to extract the username from this list, what shall i do? Also what is suser here?

Answer 1

I don't know why they choose the name suser , but it's actually a namedtuple.

That shouldn't matter, you get the name of a user like so:

>>> import psutil
>>> users = psutil.users()
>>> first_user = users[0]
>>> name = first_user.name
>>> print(name)
'vibhcool'

In short:

>>> import psutil
>>> print(psutil.users()[0].name)
'vibhcool'

Answer 2

I got the answer, (sorry i am bad at googling)

psutil.users() outputs a list, so it can be traversed using for loop

users = psutil.users()
    for user in users:
        print(user.name)

Answer 3

这样做不是很安全，而是：

users_name = [user[0] for user in psutil.users()]
