Python TK实现的日历

import calendar
from tkinter import *
root = Tk()
labels = [['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']]
MonthCal = calendar.monthcalendar(2020, 5)
for i in range(len(MonthCal)):
    labels.append(MonthCal[i])
for r in range(len(MonthCal) + 1):
    for c in range(7):
        if labels[r][c] == 0:
            labels[r][c] = ' '
        label = Label(root,
                      padx=5,
                      pady=5,
                      text=str(labels[r][c]))
        label.grid(row=r, column=c)
root.mainloop()
