Reading lines from a file is easy enough. My own preference
is this:
servers = open ("c:/servernames.txt").read ().splitlines ()
because it strips off the trailing line feeds, but there
are several alternatives.

It's not entirely clear what you want to log and to how many files, but
assuming that:
a) You're using the wmi module from:
http://timgolden.me.uk/python/wmi.html
b) You have a list of servers in c:\servernames.txt
c) You want the list of services from each machine
to go into a file called <servername>-services.log
then this code should at least give you an outline:
One caveat: because in Python, as in other languages,
the backslash acts as a special-character escape, you
either need to double them up in Windows filenames,
("c:\\server...") or use raw strings (r"c:\server..")
or use forward slashes ("c:/server...")
<code - untested>
import wmi
servers = open ("c:/servernames.txt").read ().splitlines ()
for server in servers:
wmi_connection = wmi.WMI (server)
with open ("%s-services.log" % server, "w") as f:
for service in wmi_connection.Win32_Service ():
f.write ("%s\t%s\n" % (service.Caption, service.State))
