Translation: Ask for help) Create data in a two-dimensional array

my code
{
  "Name": "test1",
  "CreationDate": "2022-6-17",
  "Commands": [
    {
      "Command": "if_v2",
      "Target": "${!LOOP}==1",
      "Value": "templist = [][]",
      "Description": ""
    },
    {
      "Command": "open",
      "Target": "https://kr.usembassy.gov/category/news/",
      "Value": "",
      "Description": ""
    },
    {
      "Command": "click",
      "Target": "xpath=/html/body/div[5]/section[2]/div[2]/div/main[${!LOOP}]/article/div/div/h2[2]/a",
      "Value": "",
      "Targets": [
        "xpath=/html/body/div[5]/section[2]/div[2]/div/main/article/div/div/h2[2]/a/font/font",
        "xpath=//h2[2]/a/font/font",
        "css=body > div.main-content-wrapper > section.stacking-slide.container-fluid.archivesection > div.archive-tax.alignwide.archivetemp.container > div > main:nth-child(1) > article > div > div > h2.entry-title > a > font > font"
      ],
      "Description": ""
    },
    {
      "Command": "pause",
      "Target": "1000",
      "Value": "",
      "Description": ""
    },
    {
      "Command": "storeText",
      "Target": "xpath=/html/body/div[5]/section[2]/div[1]/div[4]",
      "Value": "CON_DATE",
      "Description": ""
    },
    {
      "Command": "storeText",
      "Target": "xpath=/html/body/div[5]/section[2]/div[2]/div",
      "Value": "CONTENT",
      "Description": ""
    },
    {
      "Command": "comment",
      "Target": "echo // ${CON_DATE}",
      "Value": "",
      "Description": ""
    },
    {
      "Command": "comment",
      "Target": "echo // ${CONTENT}",
      "Value": "",
      "Description": ""
    },
    {
      "Command": "executeScript_Sandbox",
      "Target": "",
      "Value": "",
      "Description": ""
    },
    {
      "Command": "",
      "Target": "",
      "Value": "",
      "Description": ""
    }
  ]
}

I want to make it in the form below.

templist = [${con_date}][${content}]

python code like
n=0
while (n = 1000)
   a = list()
   a.append([con_date][title])
   n+=1

print(a) ==> [2022.06.17][lalalalbabbalblala], ....................

After making it in the above format, I want to make output with the json file.
It is so hard because there is no API translation in my native language.
Give me a hand. Thank you.

Hi, here is some information on how to work with arrays: Arrays in UI vision Selenium IDE++ - #6

Note that you must use executeScript not executeScript_Sandbox.
