我需要在python中将他输出转换为Json格式。在Python中将表格CLI输出转换为JSON格式

我该怎么办？

1 。输出应该是什么样子，以及2.你尝试过的什么都不起作用？ –

我想说你必须使用复杂的常规ex或有状态行解析器。不幸的是，两者都会处于挑战和丑陋之间。 –

您可以使用'---'分隔符来定义每个键和值行的切片以构建每个键值。（从你的榜样，我猜有多个“国防部”，与时俱进的独特国防部的价值观，所以我用这个领域的整体蓄电池键。）

感谢Paul的建议。上面的代码完美地适用于一个模块。然而，对于输入1.它的抛出键错误，因为这里有一个新的rowname'xbar'。任何想法我们如何处理这一点。此外，它不是迭代为输入2的下一组模块。 – Aftab

写完后，我有一种感觉，这将是多个模块的情况。重写为使用itertools.groupby抽出一组行，并在有一组非数据行的情况下进行一些错误检查。你从这里学不到很多Python，但也许这对你来说是一个有用的代码示例。 – PaulMcG

我有一个解决方案，但它是不漂亮。假设你的整个输出是在text。

import re 
lines = text.split("\n") 
keylines = [line for i, line in enumerate(lines) if len(lines)>(i+1) and "---" in lines[i+1]] 
vallines = [line for i, line in enumerate(lines) if i!=0 and "---" in lines[i-1]] 
keys = re.split(" +", " ".join(keylines)) 
vals = re.split(" +", " ".join(vallines)) 
result = dict(zip(keys, vals))

输出：

{ 
    "Mod": "1", 
    "Ports": "48", 
    "Module-Type": "1/2/4/8 Gbps FC/Supervisor-3", 
    "Model": "DS-C9148-K9-SUP", 
    "Status": "active *", 
    "Sw": "6.2(17)", 
    "Hw": "1.1", 
    "World-Wide-Name(s) (WWN)": "20:01:54:7f:ee:df:88:f8 to 20:30:54:7f:ee:df:88:f8", 
    "MAC-Address(es)": "c0-8c-60-65-82-dc to c0-8c-60-65-82-df", 
    "Serial-Num": "JAF1736ALLM" 
}

它做以下假设，当他们是不是真的会打破：

没有值包含连续多个空格。
“字段”之间至少有两个空格。
在与破折号的行中，至少有一个3破折号的段。
