问题是我希望它忽略日期,只考虑时间因素.这是我有的:

import time
from time import mktime
from datetime import datetime

def getTimeCat(Datetime):
    # extract time categories
    str_time = datetime.strptime(Datetime, "%m/%j/%y %H:%M")
    ts = datetime.fromtimestamp(mktime(str_time))

    # --> Morning = 0400-1000
    mornStart = datetime.time(4, 0, 1)
    mornEnd = datetime.time(10, 0, 0)

    # --> Midday = 1000-1600
    midStart = datetime.time(10, 0, 1)
    midEnd = datetime.time(16, 0, 0)

    # --> Evening = 1600-2200
    eveStart = datetime.time(16, 0, 1)
    eveEnd = datetime.time(22, 0, 0)

    # --> Late Night = 2200-0400
    lateStart = datetime.time(22, 0, …

我试图转换两个"持续时间",但我目前收到的是TypeError由于一个是一个datetime.timedelta和一个是datetime.time:

TypeError: unorderable types: datetime.time() <= datetime.timedelta()

将a转换datetime.time为a 的有效方法是datetime.timedelta什么？

我已经检查了文档,并且没有内置的方法来在这两种类型之间进行转换.
