python tkinter制作日历界面的简单步骤

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

root = tk.Tk()
root.title("简易日历")
root.geometry("400x300")

today = datetime.now()
year = today.year
month = today.month

def show_calendar(year, month):
    # 清除旧内容
    for widget in frame.winfo_children():
        widget.destroy()
<pre class='brush:python;toolbar:false;'># 显示星期标题
days = ["日", "一", "二", "三", "四", "五", "六"]
for i, day in enumerate(days):
    label = tk.Label(frame, text=day, font=("Arial", 10), width=4, height=2)
    label.grid(row=0, column=i)

# 获取当月日历（二维列表）
cal = calendar.monthcalendar(year, month)
for r, week in enumerate(cal, start=1):
    for c, day in enumerate(week):
        if day == 0:
            text = ""
        else:
            text = str(day)
        label = tk.Label(frame, text=text, font=("Arial", 10), width=4, height=2,
                        relief="solid")
        label.grid(row=r, column=c)

# 年份选择
year_var = tk.StringVar(value=year)
year_combo = ttk.Combobox(root, textvariable=year_var, values=list(range(year-10, year+11)), width=6)
year_combo.grid(row=0, column=0, padx=5, pady=5)
<h1>月份选择</h1><p>month_var = tk.StringVar(value=month)
month_combo = ttk.Combobox(root, textvariable=month_var, values=list(range(1, 13)), width=4)
month_combo.grid(row=0, column=1, padx=5, pady=5)</p><h1>更新按钮</h1><p>update_btn = tk.Button(root, text="显示", command=lambda: show_calendar(int(year_var.get()), int(month_var.get())))
update_btn.grid(row=0, column=2, padx=5, pady=5)</p>

frame = tk.Frame(root)
frame.grid(row=1, column=0, columnspan=3)
