如何在python脚本中将IP地址从文本文件分配给主机名

Question

I am able to retreive and assign username and password from text and pass it to ftplib for "ftp.login"

How can I do the same thing for an IP address in a text file that I want to pass to "ftplib.FTP("0.0.0.0")" instead of the (0.0.0.0) want to replace it with "ftplib.FTP(hostname)?

here is the script:

#!/usr/bin/env python

import ftplib
import os
import sys
import paramiko
import datetime
import pickle
import ftplib as ftp
import socket




login = {}
with open('hostname1.txt', 'r') as g:
   for line in g:
       hostname = line.strip()
       login[hostname] = hostname


credentials = {}
with open('Usernames.txt', 'r') as f:
    for line in f:
        username, password = line.strip().split(':')
        credentials[username] = password

try:
        try:
            print "Connecting to 192.168.189.130"
            ftp = ftplib.FTP(hostname)
            ftp.login(username, password)
            ftp.cwd('dir1')
            ftp.retrlines('LIST')
#           ftp.get()

        except ftplib.all_errors as e:
            print(e)
except ftp.login as s:
    print (s)

Thanks "Praneeth" for quick response!

Answered my own question.

This works!

simple mistake on my part... did not remove the double quotes "" in the () with the ftplib.FTP(hostname) line.....

Please use it works great!

#!/usr/bin/env python

import ftplib
import os
import sys
import paramiko
import datetime
import pickle
import ftplib as ftp
import socket




login = {}
with open('hostname1.txt', 'r') as g:
   for line in g:
       hostname = line.strip()
       login[hostname] = hostname


credentials = {}
with open('Usernames.txt', 'r') as f:
    for line in f:
        username, password = line.strip().split(':')
        credentials[username] = password

try:
        try:
            print "Connecting to 0.0.0.0"
            ftp = ftplib.FTP(hostname)
            ftp.login(username, password)
            ftp.cwd('dir1')
            ftp.retrlines('LIST')
#           ftp.get()

        except ftplib.all_errors as e:
            print(e)
except ftp.login as s:
    print (s)
