[PYTHON] Implementieren Sie einen Datumssetzer in Tkinter

Der Quellcode lautet wie folgt.

import tkinter as tk
from tkinter import ttk
import datetime
import calendar

year_list = ['2020', '2021']
month_list = [str(date).zfill(2) for date in range(1, 13)]

hours_list = [str(date).zfill(2) for date in range(24)]
minutes_list = [str(date).zfill(2) for date in range(60)]
seconds_list = [str(date).zfill(2) for date in range(60)]

Die Differenz am letzten Tag in Abhängigkeit von Jahr und Monat wurde vom Kalendermodul behandelt. Nach dem Start wird der folgende Bildschirm angezeigt, in dem Sie Datum und Uhrzeit auswählen können. キャプチャ.PNG
