使用 python for 循环创建时间列表

Question

我想以 00:00 到 23:45 的格式创建时间列表。我认为这可以使用 for 循环来完成，但我不确定如何去做。只要使用正确的 00:00 格式，我不关心列表中值的类型。现在我只是用设置值实例化列表，代码如下所示。谢谢您的帮助！'''Pythontimes = ['00:00', '00:15' , '00:30' , '00:45' ,         '01:00', '01:15' , '01:30' , '01:45' ,         '02:00', '02:15' , '02:30' , '02:45' ,         '03:00', '03:15' , '03:30' , '03:45' ,         '04:00', '04:15' , '04:30' , '04:45' ,         '05:00', '05:15' , '05:30' , '05:45' ,         '06:00', '06:15' , '06:30' , '06:45' ,         '07:00', '07:15' , '07:30' , '07:45' ,         '08:00', '08:15' , '08:30' , '08:45' ,         '09:00', '09:15' , '09:30' , '09:45' ,         '10:00', '10:15' , '10:30' , '10:45' ,         '11:00', '11:15' , '11:30' , '11:45' ,         '12:00', '12:15' , '12:30' , '12:45' ,         '13:00', '13:15' , '13:30' , '13:45' ,         '14:00', '14:15' , '14:30' , '14:45' ,         '15:00', '15:15' , '15:30' , '15:45' ,         '16:00', '16:15' , '16:30' , '16:45' ,         '17:00', '17:15' , '17:30' , '17:45' ,         '18:00', '18:15' , '18:30' , '18:45' ,         '19:00', '19:15' , '19:30' , '19:45' ,         '20:00', '20:15' , '20:30' , '20:45' ,         '21:00', '21:15' , '21:30' , '21:45' ,         '22:00', '22:15' , '22:30' , '22:45' ,         '23:00', '23:15' , '23:30' , '23:45' ]'''

Answer 1

您可以从 datetime 包创建一个datetime对象，然后使用它strftime('%H:%M')来将其转换为字符串：

from datetime import datetime

from datetime import timezone

[datetime.fromtimestamp(d, tz=timezone.utc).strftime('%H:%M') for d in range(0, 60*60*24, 15*60)]

这给了我们：

>>> [datetime.fromtimestamp(d, tz=timezone.utc).strftime('%H:%M') for d in range(0, 60*60*24, 15*60)]

['00:00', '00:15', '00:30', '00:45', '01:00', '01:15', '01:30', '01:45', '02:00', '02:15', '02:30', '02:45', '03:00', '03:15', '03:30', '03:45', '04:00', '04:15', '04:30', '04:45', '05:00', '05:15', '05:30', '05:45', '06:00', '06:15', '06:30', '06:45', '07:00', '07:15', '07:30', '07:45', '08:00', '08:15', '08:30', '08:45', '09:00', '09:15', '09:30', '09:45', '10:00', '10:15', '10:30', '10:45', '11:00', '11:15', '11:30', '11:45', '12:00', '12:15', '12:30', '12:45', '13:00', '13:15', '13:30', '13:45', '14:00', '14:15', '14:30', '14:45', '15:00', '15:15', '15:30', '15:45', '16:00', '16:15', '16:30', '16:45', '17:00', '17:15', '17:30', '17:45', '18:00', '18:15', '18:30', '18:45', '19:00', '19:15', '19:30', '19:45', '20:00', '20:15', '20:30', '20:45', '21:00', '21:15', '21:30', '21:45', '22:00', '22:15', '22:30', '22:45', '23:00', '23:15', '23:30', '23:45']

Answer 2

只用纯 for 循环来做到这一点：

times = []

for hour in range(24):

    for minute in range(0, 60, 15):

        times.append('{:02d}:{:02d}'.format(hour, minute))

Answer 3

这是做你想做的另一种方法：

def time_interval(hour, minute, interval):

    return [

        f"{str(i).zfill(2)}:{str(j).zfill(2)}" 

        for i in range(hour)

        for j in range(minute)

        if j % interval == 0

    ]

times = time_interval(24, 60, 15)

print(times)

输出：

['00:00', '00:15', '00:30', '00:45', '01:00', '01:15', '01:30', '01:45', '02:00', '02:15', '02:30', '02:45', '03:00', '03:15', '03:30', '03:45', '04:00', '04:15', '04:30', '04:45', '05:00', '05:15', '05:30', '05:45', '06:00', '06:15', '06:30', '06:45', '07:00', '07:15', '07:30', '07:45', '08:00', '08:15', '08:30', '08:45', '09:00', '09:15', '09:30', '09:45', '10:00', '10:15', '10:30', '10:45', '11:00', '11:15', '11:30', '11:45', '12:00', '12:15', '12:30', '12:45', '13:00', '13:15', '13:30', '13:45', '14:00', '14:15', '14:30', '14:45', '15:00', '15:15', '15:30', '15:45', '16:00', '16:15', '16:30', '16:45', '17:00', '17:15', '17:30', '17:45', '18:00', '18:15', '18:30', '18:45', '19:00', '19:15', '19:30', '19:45', '20:00', '20:15', '20:30', '20:45', '21:00', '21:15', '21:30', '21:45', '22:00', '22:15', '22:30', '22:45', '23:00', '23:15', '23:30', '23:45']
