I have this value taken from SQL "[4,8,12,16]". Python treats it as string but when hardcoded to rrule it seems to work if today in rrule(DAILY, dtstart = start_date, byhour=[4,8,12,16], byminute=row.minute, bysecond=0):
How to convert the string so that rrule function will accept it? Thanks for the help.
