Question

我正尝试在python中读取json文件，并且想将长值分成多行以使其更易于阅读。

例如JSON文件：

mem的值太长，因此我想使其多行。

{
    "resource":{
        "cpu": ["host, usage_system, usage_user, usage_iowait", "1=1"],
        "mem": ["host, active/(1024*1024) as active, available/(1024*1024) as available, available_percent, buffered/(1024*1024) as buffered, cached/(1024*1024) as cached, swap_cached/(1024*1024) swap_cached, swap_total/(1024*1024) swap_total, total/(1024*1024) mem_total, used/(1024*1024) mem_used", "1=1"],
        "net": ["host, bytes_recv, bytes_sent, packets_recv, packets_sent", "1=1 and interface != 'all'"]
    }
}

我想像下面这样设定值。

{ "resource":{
                "cpu": ["host, usage_system, usage_user, usage_iowait", "1=1"],
                "mem": ["host, active/(1024*1024) as active, available/(1024*1024) as available, 
    available_percent, buffered/(1024*1024) as buffered, 
    cached/(1024*1024) as cached, swap_cached/(1024*1024) swap_cached, 
    swap_total/(1024*1024) swap_total, 
    total/(1024*1024) mem_total, used/(1024*1024) mem_used", "1=1"],
                "net": ["host, bytes_recv, bytes_sent, packets_recv, packets_sent", "1=1 and interface != 'all'"]
            }
        }

谢谢！

好的，因此您可能要在json中列出字符串列表，然后将它们与“” .join（）组合。例如， json.json

{
    "multiline": [
        "this is a re",
        "ally long st",
        "ring, so I n",
        "eed to make ",
        "it one line"
    ]
}

multiline.py

import json
with open("json.json", "r") as jsonfile:
    stringlist = json.loads(jsonfile.read())["multiline"]
    result = "".join(stringlist)
    print(result)

在JSON中将一行分成多行
