I have a json file with the below format [seconds * min * hour * day of month * month * day of week]

{
    "cronExpression": "0 48 10 ? * TUE-SAT"
}

and I want to read the above json and convert it to the below,

 "When": {
        "WeekDays": ["TUE","WED","THU","FRI","SAT"],
        "MonthDays": ["NONE"],
        "FromTime": "1048"
      }

I am new to Python, and is there any lib to take the string TUE-SAT and convert it to ["TUE","WED","THU","FRI","SAT"] I am thinking of taking the string and use switch case to add manually append the string, but this could leads to complex logic with different propositions.

The TUE-SAT – could be dynamic such as MON-WED or FRI-SAT

any help appreciated. thanks!
