如何从日期获得当天的数量？

var today = new Date();
var day = today.getDay();
var dayNum = today.getDate();

from datetime import datetime

today = datetime.today()
day = today.strftime("%A")
dayNum = today.strftime("%d")

import unittest
from datetime import datetime

class TestGetTodayNumber(unittest.TestCase):
    def test_get_today_number(self):
        today = datetime.today()
        day = today.strftime("%A")
        dayNum = today.strftime("%d")
        self.assertEqual(dayNum, today.day)

SELECT DATE_FORMAT(date_column, '%Y-%m-%d') AS today_date FROM table_name;

date +"%A %d"
