npyscreen 有小部件吗 "DateCombo" and "TitleDateCombo" 用于挑选日期。

如果没有,是否有推荐的第三方库?

下面是一个使用npyscreen的示例:

#! /usr/bin/env python3
# -*- coding: utf-8 -*-

import npyscreen

class DateForm(npyscreen.Form):
    def afterEditing(self):
        self.parentApp.setNextForm(None)

    def create(self):
        self.date = self.add(npyscreen.TitleDateCombo, name="Date")

class TestApplication(npyscreen.NPSAppManaged):
    def onStart(self):
        new_user = self.addForm("MAIN", DateForm, name="Read Date")

if __name__ == "__main__":
    TestApplication().run()

似乎python库 urwid

additional_urwid_widgets.DatePicker 和 pip .

为了一个 独立示例 ,它演示了小部件的功能,请参见 here .

更多(更简单) ,请参见 here .

再来一次 详细说明 有关参数和选项的详细信息,请参见 the corresponding github wiki entry .

一些例子

最小

#! /usr/bin/env python3
# -*- coding: utf-8 -*-

from additional_urwid_widgets import DatePicker, MODIFIER_KEY      # installed via pip
import urwid                                                       # installed via pip

# Color schemes that specify the appearance off focus and on focus.
PALETTE = [("reveal_focus", "black", "white")]

dp = DatePicker(highlight_prop=("reveal_focus", None))        # By default, the focused picker is not highlighted!

pile = urwid.Pile([urwid.Text("press additionally the key modifier (default is 'ctrl')."),
                   urwid.Divider(" "),
                   dp])

loop = urwid.MainLoop(urwid.Filler(pile, "top"),
                      PALETTE)
loop.run()

今天不行

#! /usr/bin/env python3
# -*- coding: utf-8 -*-

import datetime
from additional_urwid_widgets import DatePicker, MODIFIER_KEY      # installed via pip
import urwid                                                       # installed via pip

# Color schemes that specify the appearance off focus and on focus.
PALETTE = [("reveal_focus", "black", "white")]

not_today = datetime.date(2018, 2, 20)

dp = DatePicker(initial_date=not_today,
                highlight_prop=("reveal_focus", None))        # By default, the focused picker is not highlighted!

pile = urwid.Pile([urwid.Text("press additionally the key modifier (default is 'ctrl')."),
                   urwid.Divider(" "),
                   dp])

loop = urwid.MainLoop(urwid.Filler(pile, "top"),
                      PALETTE)
loop.run()

不,urwid没有datepicker,它是一个需要实现的复杂的小部件,应该有自己的项目,因为这些小部件通常需要考虑日期格式、语言环境等。

我不知道有哪一个urwid库实现了它,通过快速扫描我知道的那些库也找不到。

您可以尝试购买一个库,但您可能会有更好的运气实现一个自己的具体需要。
