我知道我想做的是可能的。我只是無(wú)法弄清楚。我希望有更多在python中處理日期的經(jīng)驗(yàn)的人能對(duì)我有所幫助。我試圖創(chuàng)建一個(gè)日期范圍的列表，其中列表中的每個(gè)元素都包含一個(gè)日期以及該日期代表的是星期幾。到目前為止，這就是我所擁有的。from datetime import datetimedate_format = "%b %d, %Y"a = datetime.strptime('Feb 16, 2013', date_format)b = datetime.strptime('Aug 11, 2013', date_format)delta = b - adelta = delta.days # that's itprint aprint bbase = a dateList = [ base + timedelta(days=x) for x in range(0,delta) ]print dateList如您所見(jiàn)，一周中的任何一天我都沒(méi)有任何東西-因此它甚至不是正確的元組形式的表達(dá)式。我已經(jīng)找到并閱讀了我認(rèn)為是星期幾的正確文檔（請(qǐng)參閱date.weekday（）），但似乎無(wú)法正常工作。也許是因?yàn)槲也惶私鈱?duì)象。我也不知道如何更改timedelta返回的格式-即datetime.datetime（2013，4，25，0，0）-因?yàn)槲也恍枰谠M之前加上datetime.datetime一旦創(chuàng)建它們。我歡迎任何有關(guān)如何做自己想做的事情的評(píng)論或反饋-假設(shè)有可能。預(yù)先感謝您的任何建議。

該datetime對(duì)象本身有一個(gè).weekday()屬性。您可以將它們添加到單獨(dú)的循環(huán)中：
dateList = [(d, d.weekday()) for d in dateList]
對(duì)于您的示例代碼，它給出：

您可以通過(guò)使用一個(gè)元素創(chuàng)建一個(gè)額外的嵌套循環(huán)，將其與現(xiàn)有列表理解功能結(jié)合起來(lái)：
dateList = [(d, d.weekday()) for x in range(0,delta) for d in [base + timedelta(days=x)]]
