[PyQt] to display cotent of database between two dates

[atlass218]

The main imports in my source code are as follows:

#!/usr/bin/python3
# -*- coding: utf-8 -*-

# import os :
import os, errno
from os import path
import pathlib
import sys
import logging

# PyQT5 :  
from PyQt5.QtWidgets import *
from PyQt5.QtCore import* 
from PyQt5.QtGui import *

#date / time :
import time
import datetime
import datetime as dt
from datetime import datetime

# import   sqlite3 for database :
import sqlite3

thank you for accompanying me all this long time to find the solution to my problem
