[Tutor] For loop question

[STREET Gideon (SPARQ)]

Hi all,

Been trying to understand why the following doesn't work:

HostFile = open("hosts.txt", 'r')
host = HostFile.readlines()

for item in host:
    print "Connecting to device",item
    tn = telnetlib.Telnet(item)
...
Do some other stuff here
...

I get the following error:

Traceback (most recent call last):
  File "testtelnet.py", line 14, in ?
    tn = telnetlib.Telnet(item)
  File "c:\gideon\python24\lib\telnetlib.py", line 208, in __init__
    self.open(host, port)
  File "c:\gideon\python24\lib\telnetlib.py", line 225, in open
    for res in socket.getaddrinfo(host, port, 0, socket.SOCK_STREAM):
socket.gaierror: (11001, 'getaddrinfo failed')

The hosts.txt file contains device names on separate lines.  If I remove
the tn = .... Line the for loop iterates as I expect it to.  Can't
understand why I can't pass "item" as a string to the telnetlib.Telnet
command.

Cheers

Gideon
