Merge two files with Python

1 format as follows

In the use of Zabbix API to bulk add the host, you need to deal with IP and hostname, on the basis of borrowing others to write the PY program, they have modified the following script for their own use. IP and hostname are a unified format when needed.

1.1. 1.1 2.2. 2.2 3.3. 3.3 4.4. 4.4

$ cat Hostname.txttx-1TX-2TX-3TX-4

Finally, you need to merge into the following format

1 tx-1,1.1. 1.1 2 tx-2,2.2. 2.2 3 tx-3,3.3. 3.3 4 tx-4,4.4. 4.4

On script 1:

1 Cat ip_hostname.py2 3#!/usr/bin/env python4#_ *_coding:utf-8_*_5 6 Import Itertools7 8With open ("Ip.txt") asF:9Txt1=[r.rstrip ("\ n") forRinchf.readlines ()]TenWith open ("Hostname.txt") asF: OneTxt2=[r.rstrip ("\ n") forRinchf.readlines ()] A  -  -Result=itertools.izip_longest (txt1,txt2,fillvalue=' ') the#[print (R) forRinchresult] -  -With open ("Result.txt","w+") asF: -[F.write (','. Join (R) +"\ n") forRinchResult

or Use parameters: (concise)

1Cat ip-hostname.py
#!/usr/bin/env python2# coding:utf-83 4 Import SYS5 Import CSV6file1=sys.argv[1]7file2=sys.argv[2]8 9Ip=open (File1,'R'). ReadLine (). Strip ()TenHostname=open (File2,'R'). ReadLine ().

ReadAll () -  thename=ip+','+hostname+'\ n' -  -  -With open ('Names.txt','W') asFile3: +      forIinchfile1: -writer = File3.write (name)

Run:

Python ip-hostname.py ip.txt Hostname.txt
