tkinter应用程序是否允许用户选择日期？
答案 0 :(得分：18)
不，Tk不包含日期选择器小部件。您可以尝试使用几个Python日历小部件：

答案 1 :(得分：10)
不是我能找到的。对于任何想要在未来这样做的人：
我使用tkSimpleDialog和ttkcalendar.py（来自this SO post的修改）来制作CalendarDialog。我的github上提供了这三个文件的修改版本。
以下是我CalendarDialog.py中的代码：
import Tkinter
import ttkcalendar
import tkSimpleDialog
class CalendarDialog(tkSimpleDialog.Dialog):
"""Dialog box that displays a calendar and returns the selected date"""
def body(self, master):
self.calendar = ttkcalendar.Calendar(master)
self.calendar.pack()
def apply(self):
self.result = self.calendar.selection
# Demo code:
def main():
root = Tkinter.Tk()
root.wm_title("CalendarDialog Demo")
def onclick():
cd = CalendarDialog(root)
print cd.result
button = Tkinter.Button(root, text="Click me to see a calendar!", command=onclick)
button.pack()
root.update()
root.mainloop()
if __name__ == "__main__":
main()
答案 2 :(得分：8)
尝试以下操作：
from tkinter import *
from tkcalendar import Calendar,DateEntry
root = Tk()
cal = DateEntry(root,width=30,bg="darkblue",fg="white",year=2010)
cal.grid()
root.mainloop()
应通过tkcalendar命令下载并安装pip install tkcalender库。
答案 3 :(得分：7)
如果有人仍然需要这个 - 这是一个使用tkcalendar包创建Calendar和DateEntry小部件的简单代码。
pip install tkcalendar [用于安装包]
try:
import tkinter as tk
from tkinter import ttk
except ImportError:
import Tkinter as tk
import ttk
from tkcalendar import Calendar, DateEntry
def example1():
def print_sel():
print(cal.selection_get())
top = tk.Toplevel(root)
cal = Calendar(top,
font="Arial 14", selectmode='day',
cursor="hand1", year=2018, month=2, day=5)
cal.pack(fill="both", expand=True)
ttk.Button(top, text="ok", command=print_sel).pack()
def example2():
top = tk.Toplevel(root)
ttk.Label(top, text='Choose date').pack(padx=10, pady=10)
cal = DateEntry(top, width=12, background='darkblue',
foreground='white', borderwidth=2)
cal.pack(padx=10, pady=10)
root = tk.Tk()
s = ttk.Style(root)
s.theme_use('clam')
ttk.Button(root, text='Calendar', command=example1).pack(padx=10, pady=10)
ttk.Button(root, text='DateEntry', command=example2).pack(padx=10, pady=10)
root.mainloop()
答案 4 :(得分：4)
不，但您可以从格式化字符串中将其作为日期时间元素从用户处获取..
示例：
import datetime
userdatestring = '2013-05-10'
thedate = datetime.datetime.strptime(userdatestring, '%Y-%m-%d')
结帐http://docs.python.org/2/library/datetime.html#strftime-strptime-behavior。它很方便，虽然不是最友好的约会方式。
答案 5 :(得分：2)
这里的答案提供了您所要求的大部分内容，但我感到它们都不是完全令人满意的。作为Tkinter的新手，我需要更多的帮助。我的投诉：
非常感谢以前为我提供帮助的答案，这是我的版本。
def get_date():
import tkinter as tk
from tkinter import ttk
from tkcalendar import Calendar, DateEntry
def cal_done():
top.withdraw()
root.quit()
root = tk.Tk()
root.withdraw() # keep the root window from appearing
top = tk.Toplevel(root)
cal = Calendar(top,
font="Arial 14", selectmode='day',
cursor="hand1")
cal.pack(fill="both", expand=True)
ttk.Button(top, text="ok", command=cal_done).pack()
selected_date = None
root.mainloop()
return cal.selection_get()
selection = get_date()
print(selection)

这就是我们在tkinter中编写python datepicker的方法。

对于更新的python家伙应该使用以下命令：pip3 install tkcalendar
它将开始安装在他们的CMD中。成功之后。
使用此方法：来自tkcalendar import Calendar
