PyGTK 循环中的时间日期管理

Question

我正在尝试为 Ubuntu 构建一个关机暂停程序，但总体而言，我仍然在努力掌握 Python。

PyGTK 甚至是基于的，因此我不太清楚如何进行时间/日期管理。有没有人有关于 PyGTK 中时间或日期甚至日历管理的资源。

我需要能够检查今天的日期并将其与用户想要的日期进行比较。任何帮助都将不胜感激。

以下是贪睡器背后的代码：

你可能想要使用datetime模块，更具体地说datetime.date如果您只想要日期而不是时间，则需要类别。

>>> from datetime import date
>>> today = date.today()
>>> today
datetime.date(2012, 11, 12)
>>> today.isoformat()
'2012-11-12'
>>>

编辑 您可以使用 GObject 计时器每 x 秒检查一次。如下所示（未经测试）：

import time
from gi.repository import GObject

def _check_time_timer(self):
    if time.time() >= USER_TIME:
        # Do your action here
        print "Time has been reached!"
        # Return False to stop timer
        return False
    # Return True to keep the timer going
    return True

# Check the user time every 4 seconds, change as needed
GObject.timeout_add_seconds(4, _check_time_timer)
