Help adding a loop inside a loop

[Extra]

Thanks, that helped clean up the SQL part of the code, but I'm still confused on the scheduler part of the code.

So this function takes in the reminder & it's scheduled date and time, then it calls the send_reminder function but I don't get what the schedule_time.timestamp() does?

def schedule_reminder(reminder, date, time):
    """Schedule a reminder"""
    scheduled_time = date_and_time_to_datetime(date, time)
    schedule.enterabs(schedule_time.timestamp(), send_reminder, arguments=(reminder, scheduled_time))

And this is what I have for getting the current date & time by the way.

#--------------------------------------------------
#              Current Date & Time
#--------------------------------------------------
import datetime
currentdate = datetime.date.today()

from datetime import datetime
timeNow = datetime.now()
currentTime = timeNow.strftime("%I:%M %p")
#--------------------------------------------------

And this is what I have for my reminders:

Output:
('Test 1', '2022-10-10', '4:30 PM')
('Test 2', '2022-10-10', '5:00 PM')
