我有一个python脚本,我在其中使用dkpg -l命令根据我的需要使用perl解析了大部分输出。我正在试图做的输出是创建一个像下面这样的json结构输出文件。从我的python解析器脚本创建Json输出

我对python非常陌生,所以在这里寻找一些关于如何使用数组结构生成这样的json文件的最佳选择的提示?

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" } 

] 

} 

的Python脚本

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)

有一个库的!

import json 

使用这个,你可以把你的数据结构...并将其转换为json!

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

......基本上就是这样。分别使用json.loadsjson.load从json类和json文件加载。
你可以在 this website找到更多

P.S.如果要使用缩进打印,请尝试

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