如何在python腳本中將IP地址從文本文件分配給主機名

Question

我可以檢索文本並從文本分配用戶名和密碼，並將其傳遞給ftplib以獲取“ ftp.login”

我如何對要傳遞給“ ftplib.FTP（“ 0.0.0.0”）”的文本文件中的IP地址執行相同的操作，而不是想要將其替換為“ ftplib.FTP”的（0.0.0.0） （主機名）？

這是腳本：

#!/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)

感謝“ Praneeth”的快速回復！

回答了我自己的問題。

這可行！

我這是一個簡單的錯誤。。。沒有刪除（）中帶有ftplib.FTP（hostname）行的雙引號“”。

請使用它效果很好！

#!/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)
