先决条件: 简介 Tkinter

Python 为开发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。Python 搭配 Tkinter 输出了创建 GUI 应用程序最快最简单的方法。在本文中，我们将学习如何使用 Tkinter 创建一个 GUI Calendar 应用程序，并提供一步一步的指导。

创建 Tkinter :

• 导入模块–Tkit


• 创建主窗口(容器)


• 向主窗口添加任意数量的小部件。


• 在小部件上应用事件触发器。

图形用户界面如下所示:

让我们创建一个基于图形用户界面的日历应用程序，它可以显示用户给定年份的日历。

下面是实现:

Python 3

# 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()
