Python|使用 Tkinter 的 GUI 日历

先决条件： Tkinter 简介

Python为开发 GUI（图形用户界面）提供了多种选择。在所有的 GUI 方法中，Tkinter 是最常用的方法。带有 Tkinter 的Python输出创建 GUI 应用程序的最快和最简单的方法。在本文中，我们将学习如何使用 Tkinter 创建一个 GUI 日历应用程序，并提供分步指南。

创建一个Tkinter ：

导入模块 – Tkinter
创建主窗口（容器）
将任意数量的小部件添加到主窗口。
在小部件上应用事件触发器。

GUI 如下所示：

让我们创建一个基于 GUI 的日历应用程序，它可以显示与用户给定的给定年份相关的日历。

下面是实现：

Python3

# import all methods and classes from the tkinter  
from tkinter import *
 
# import calendar module
import calendar
 
# Function for showing the calendar of the given year
def showCal() :
 
    # Create a GUI window
    new_gui = Tk()
     
    # Set the background colour of GUI window
    new_gui.config(background = "white")
 
    # set the name of tkinter GUI window
    new_gui.title("CALENDAR")
 
    # Set the configuration of GUI window
    new_gui.geometry("550x600")
 
    # get method returns current text as string
    fetch_year = int(year_field.get())
 
    # calendar method of calendar module return
    # the calendar of the given year .
    cal_content = calendar.calendar(fetch_year)
 
    # Create a label for showing the content of the calendar
    cal_year = Label(new_gui, text = cal_content, font = "Consolas 10 bold")
 
    # grid method is used for placing
    # the widgets at respective positions
    # in table like structure.
    cal_year.grid(row = 5, column = 1, padx = 20)
     
    # start the GUI
    new_gui.mainloop()
 
     
# Driver Code
if __name__ == "__main__" :
 
    # Create a GUI window
    gui = Tk()
     
    # Set the background colour of GUI window
    gui.config(background = "white")
 
    # set the name of tkinter GUI window
    gui.title("CALENDAR")
 
    # Set the configuration of GUI window
    gui.geometry("250x140")
 
    # Create a CALENDAR : label with specified font and size
    cal = Label(gui, text = "CALENDAR", bg = "dark gray",
                            font = ("times", 28, 'bold'))
 
    # Create a Enter Year : label
    year = Label(gui, text = "Enter Year", bg = "light green")
     
    # Create a text entry box for filling or typing the information. 
    year_field = Entry(gui)
 
    # Create a Show Calendar Button and attached to showCal function
    Show = Button(gui, text = "Show Calendar", fg = "Black",
                              bg = "Red", command = showCal)
 
    # Create a Exit Button and attached to exit function
    Exit = Button(gui, text = "Exit", fg = "Black", bg = "Red", command = exit)
     
    # grid method is used for placing
    # the widgets at respective positions
    # in table like structure.
    cal.grid(row = 1, column = 1)
 
    year.grid(row = 2, column = 1)
 
    year_field.grid(row = 3, column = 1)
 
    Show.grid(row = 4, column = 1)
 
    Exit.grid(row = 6, column = 1)
     
    # start the GUI
    gui.mainloop()

输出：
