One element must be selected. How to do without a cycle?

Question

Python

I'm trying to extract the login of the user who is currently working for the PC hostname

import wmi
wmiConn = wmi.WMI(hostname)
for cs in wmiConn.Win32_ComputerSystem():
    curUser = cs.UserName

Why in this case it is impossible to write: curUser = wmiConn.Win32_ComputerSystem().UserName ?

Answer 1

Why can't you select an element by index?

import wmi
wmiConn = wmi.WMI(hostname)
curUser = wmiConn.Win32_ComputerSystem()[0].UserName

Answer 2

Well, probably because Win32_ComputerSystem returns a list...
