python tkinter 显示日历

可以使用 Python 内置的 calendar 模块和 tkinter 模块来显示日历。以下是一个简单的示例代码：

import calendar
import tkinter as tk

class CalendarGUI:
    def __init__(self, master):
        self.master = master
        self.master.title("Calendar")
        self.year = tk.StringVar()
        self.month = tk.StringVar()
        self.create_widgets()

    def create_widgets(self):
        tk.Label(self.master, text="Year:").grid(row=0, column=0)
        tk.Entry(self.master, textvariable=self.year).grid(row=0, column=1)
        tk.Label(self.master, text="Month:").grid(row=1, column=0)
        tk.Entry(self.master, textvariable=self.month).grid(row=1, column=1)
        tk.Button(self.master, text="Show", command=self.show_calendar).grid(row=2, column=0, columnspan=2)

    def show_calendar(self):
        year = int(self.year.get())
        month = int(self.month.get())
        cal = calendar.monthcalendar(year, month)
        days = ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']

        # Create header
        for i, day in enumerate(days):
            tk.Label(self.master, text=day).grid(row=3, column=i)

        # Create calendar
        for i, week in enumerate(cal):
            for j, day in enumerate(week):
                if day != 0:
                    tk.Label(self.master, text=str(day)).grid(row=i+4, column=j)

root = tk.Tk()
app = CalendarGUI(root)
root.mainloop()
