Question

这是我目前的代码......我的课程几乎没有介绍Tkinter，我们使用的书对理解如何使用Calendar库没有帮助。标签Mon / Tu / Wed / Etc工作，但日历未显示。

from tkinter import *
from time import *
from calendar import *
class Application(Frame):

    def __init__(self, master):
        Frame.__init__(self, master)
        self.grid()
        self.create_widgets()

    def create_widgets(self):

        days = ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
#create labels
        for i in range(7):
            label = Label(self, text=days[i])
            label.grid(row = 0, column = i)

        weekday, numDays = monthrange(year, month)
        week = 1
        for i in range(1, numDays + 1):
            button = Button(self, text = str(i))
            button.grid(row = week, column = weekday)

            weekday+=1
            if weekday > 6:
                week +=1
                weekday = 0

Answer 1

首先，您应该考虑最后创建主循环：

root = tk()
app = Application(root)
root.mainloop()

它现在应该可以正常工作。

Answer 2

试试这个：

from tkinter import *
from calendar import *


class Application(Frame):

    def __init__(self, master):
        Frame.__init__(self, master)
        self.grid()

        year = int(raw_input('\nEnter Year eg. 2017\n'))
        month = int(raw_input('\nEnter month number.\n'))
        self.create_widgets(year, month)

    def create_widgets(self, year, month):

        days = ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
#create labels
        for i in range(7):
            label = Label(self, text=days[i])
            label.grid(row = 0, column = i)

        weekday, numDays = monthrange(year, month)
        week = 1
        for i in range(1, numDays + 1):
            button = Button(self, text = str(i))
            button.grid(row = week, column = weekday)

            weekday += 1
            if weekday > 6:
                week += 1
                weekday = 0


mainWindow = tk()
obj = Application(root)
mainWindow.mainloop()

在计算monthrange()时，year和month变量未定义。所以我所做的是从__init__()本身获取这些变量的输入，因此在程序开始时它会询问一个月和一年。完成后，我只是将其作为参数传递给create_widget()，然后在monthrange()中使用。还添加了mainloop

Python程序可以打印给定年份的日历

导入日历库

import calendar 

def printcalendar(year): 

# printing calendar 
print(calendar.calendar(2020)) 


year = 2020
printcalendar(year)

如何在Python中开发日历GUI？
