图形界面万年历python

以下是一个简单的 Python 代码，用于创建一个基本的图形界面万年历：

import calendar
import tkinter as tk

class Calendar:
    def __init__(self, parent):
        self.parent = parent
        self.cal = calendar.TextCalendar(calendar.SUNDAY)
        self.year = 2021
        self.month = 1
        self.wid = []
        self.day_selected = 1
        self.month_selected = self.month
        self.year_selected = self.year
        self.day_name = ""
        
        self.setup()
        self.rebuild_calendar()
        
    def setup(self):
        # 标题
        header = tk.Frame(self.parent)
        header.pack(fill="x", pady=10)
        tk.Label(header, text='My Calendar', font=('Arial',20)).pack()
        
        # 月份和年份选择
        self.year_var = tk.StringVar()
        self.month_var = tk.StringVar()
        self.year_var.set(self.year)
        self.month_var.set(self.month)
        month_year_frame = tk.Frame(self.parent)
        month_year_frame.pack()
        tk.Label(month_year_frame, text='Year:', font=('Arial', 16)).grid(row=0, column=0)
        tk.Label(month_year_frame, text='Month:', font=('Arial', 16)).grid(row=0, column=2)
        year_spin = tk.Spinbox(month_year_frame, from_=1900, to=2099, width=5, font=('Arial', 16), textvariable=self.year_var, command=self.rebuild_calendar).grid(row=0, column=1)
        month_spin = tk.Spinbox(month_year_frame, values=('Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'), width=5, font=('Arial', 16), textvariable=self.month_var, command=self.rebuild_calendar).grid(row=0, column=3)
        
        # 日历主体
        self.main = tk.Frame(self.parent)
        self.main.pack()
        
        # 星期名称
        days = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday']
        for i, day in enumerate(days):
            tk.Label(self.main, text=day, font=('Arial', 16)).grid(row=1, column=i)
        
        # 日历日期
        for week in range(6):
            for day in range(7):
                self.wid.append(tk.Label(self.main, font=('Arial', 16), width=4))
                self.wid[-1].grid(row=week+2, column=day)
                self.wid[-1].bind('<Button-1>', self.day_click)
                
        # 今天按钮
        today_button = tk.Button(self.parent, text='Today', width=15, command=self.today)
        today_button.pack(pady=10)
        
    def rebuild_calendar(self):
        self.year_selected = int(self.year_var.get())
        self.month_selected = int(self.month_var.get())
        calendar_month = self.cal.monthdayscalendar(self.year_selected, self.month_selected)
        
        for i in range(len(calendar_month)):
            week = calendar_month[i]
            week_index = i+2
            for j in range(len(week)):
                day = week[j]
                wid_index = i*7+j
                if day == 0:
                    self.wid[wid_index].config(text='')
                else:
                    self.wid[wid_index].config(text=day)
                    if day == self.day_selected:
                        self.wid[wid_index].config(bg='blue')
                    else:
                        self.wid[wid_index].config(bg='#FFFFFF')
                        
        month_name = calendar.month_name[self.month_selected]
        self.year_name = self.year_selected
        self.day_name = ""
        header_text = month_name + " " + str(self.year_name)
        self.parent.title(header_text)
        
    def day_click(self, event):
        widget = event.widget
        self.day_selected = int(widget['text'])
        self.rebuild_calendar()
        
    def today(self):
        self.year_selected = 2021
        self.month_selected = 1
        self.day_selected = 1
        self.year_var.set(self.year_selected)
        self.month_var.set(self.month_selected)
        self.rebuild_calendar()

if __name__ == '__main__':
    root = tk.Tk()
    root.geometry('600x500')
    app = Calendar(root)
    root.mainloop()

这个代码使用了 `tkinter` 模块来创建图形界面，并使用 `calendar` 模块来生成万年历。在界面上，用户可以选择不同的月份和年份，可以点击日期，标记选中的日期，并且可以通过一个“今天”按钮返回到当前日期。
