将文本文件转换为 json 格式或过滤掉键值对

Question

我尝试执行一项可以从 txt 文件中找出键和值的任务。 我心里有一些想法。 1.使用正则表达式 2.将txt转成json。

我在过滤和转换格式时遇到了困难。有什么好的方法可以做到这一点，或者任何可用的 api 都可以执行这样的任务吗？

txt 文件：

json 文件：

{
   System: {
      Host:'ict-vm',
      Kernel:'4.4.0-53-generic i686 (32 bit)',
       .....
      },
   Machine:{
      System: 'ASUSTeK (portable)'
    }
}

预期结果：我可以使用键获取值

print(node['System'])

输出：

ASUSTeK (portable)

Answer 1

如果文件格式是固定的并且没有嵌套的字典，那么这可以很容易地转换为字典使用

import re
x="""System:       Host: ict-vm Kernel: 4.4.0-53-generic i686 (32 bit) Desktop: MATE 1.16.1  Distro: Linux Mint 18.1 Serena
Machine:      System: ASUSTeK (portable) product: N43SN v: 1.0 Mobo: ASUSTeK model: N43SN v: 1.0 serial: NB-1234567890 Bios: American Megatrends v: N43SN.412 date: 09/21/2011"""
y = re.findall(r"(\S+):\s*(.*?)(?=\s*\S+:|$)",x)
d={}
for i,j in y:
    if not j:
        d[i]={}
        k=d[i]
    else:
        k[i]=j
print d

输出：

{'Machine': {'product': 'N43SN', 'Mobo': 'ASUSTeK', 'System': 'ASUSTeK (portable)', 'Bios': 'American Megatrends', 'v': 'N43SN.412', 'date': '09/21/2011', 'model': 'N43SN', 'serial': 'NB-1234567890'}, 'System': {'Kernel': '4.4.0-53-generic i686 (32 bit)', 'Host': 'ict-vm', 'Distro': 'Linux Mint 18.1 Serena', 'Desktop': 'MATE 1.16.1'}}

您可以使用d['Machine']['System']访问

输出：ASUSTeK (portable)

编辑：

对于新的输入文件，我们需要调整正则表达式。所以使用

\s*([^:\n]+):\s*((?:(?!: |\n)[\s\S])*)(?=\s+[^:\n]+:|$)
