從我的python解析器腳本創建Json輸出

Question

我有一個編寫的python腳本，其中我根據需要使用dkpg -l命令的perl解析大部分輸出。 我想對輸出進行的操作是創建一個json結構輸出文件，如下所示。

我是python的新手，因此想在這里找到一些最佳建議，以生成具有數組結構的json文件，這是我最好的選擇？

Json文件

{

 "hostname": "xyz-abc-m001",
 "publicIP": "111.00.00.xxx",
 "privateIP": "10.xxx.xx.61",
 "kernal": "4.4.0-72-generic #93-Ubuntu",
 "package": [
   { "name":"nfs-common", "installed":"1:1.2.8-9ubuntu12", "available":"1:1.2.8-9ubuntu12.1" },
   { "name":"grub-common", "installed":"2.02~beta2-36ubuntu3.8", "available":"2.02~beta2-36ubuntu3.9" },
   { "name":"wget", "installed":"1.17.1-1ubuntu1.1", "available":"1.17.1-1ubuntu1.2" }

 ]

}

Python腳本

import socket
import os
import subprocess
from subprocess import Popen, PIPE


#Getting Hostname of the machine
hostname=socket.gethostname()

#Getting private IP of the machine on eth0 
f = os.popen(" ip addr show eth0 | grep -Po 'inet \K[\d.]+' ")
private_ip=f.read()

#Getting public IP of the machine on eth1 
f = os.popen(" ip addr show eth1 | grep -Po 'inet \K[\d.]+' ")
public_ip=f.read()

#Getting currently running linux kernal
f = os.popen(" uname -a | awk '{print $3, $4}' ")
running_kernal=f.read()        


pipe = Popen(" apt-get --just-print upgrade 2>&1 | perl -ne 'if (/Inst\s([\w,\-,\d,\.,~,:,\+]+)\s\[([\w,\-,\d,\.,~,:,\+]+)\]\s\(([\w,\-,\d,\.,~,:,\+]+)\)? /i) {print \"$1 $2 $3\n\"} ' ", shell=True, stdout=PIPE)

for line in pipe.stdout:
    parts = line.split() # split line into parts
    if len(parts) > 1:   # if at least 2 parts/columns
        print "Hostname = %s  PublicIP = %s PrivateIP = %s Package name = %s INSTALLED  = %s  AVAILABLE = %s kernal = %s " % (hostname, public_ip, private_ip, parts[0], parts[1], parts[2], running_kernal)

有一個圖書館！

import json

使用此方法，您可以獲取數據結構...並將其轉換為json！

data = [1, 2, 3, {"hello world":42}]
myjson = json.dumps(data)

...基本上就是這樣。 使用json.loads和json.load分別從json類和json文件加載。

PS如果要打印縮進，請嘗試

some_dictionary = {'hostname':hostname, 'PublicIP':publicIp, etc}
print(json.dumps(some_dictionary, indent=4))`
