python - 在python中计算两个小时变量之间的差异

Question

我目前正在开发一个程序，该程序将计算两个时间点之间的小时差。变量将始终处于同一日期。所以对我来说唯一重要的是时间。我计划使用日期时间，但如果有其他导入，我会开放其他示例

    # This is just a ruff idea of how it should work, but im aware it doesn't work
    var1 = datetime.now().striftime('%H:%M')
    var2 = 14:55  # This is just an example

    vardiff = var2 - var1  # var2 is always bigger than var1

    print(vardiff)

How do I find the time difference between two datetime objects in python? :

>>> import datetime
>>> first_time = datetime.datetime.now()
>>> later_time = datetime.datetime.now()
>>> difference = later_time - first_time
>>> seconds_in_day = 24 * 60 * 60
datetime.timedelta(0, 8, 562000)
>>> divmod(difference.days * seconds_in_day + difference.seconds, 60)
(0, 8)      # 0 minutes, 8 seconds

据此您可以通过以下方式获取小时数

import datetime
first_time = datetime.datetime.strptime('12:00', '%H:%M')
later_time = datetime.datetime.now()
difference = later_time - first_time
hours, remainder = divmod(difference.seconds, 3600)
minutes,seconds=divmod(remainder,60)
