Python 如何显示给定时区内时钟变化所经过的实际时间

当“欧洲/伦敦”时间从英国夏令时变为格林威治标准时，我如何准确反映经过的时间

代码：

我如何显示此时，如果一分钟过去，该时区中的新时间实际上将提前59分钟？

最好以UTC（显式）计算并在打印/输出时解析到特定时区：

from datetime import datetime, timedelta
from pytz import timezone

x = datetime(year=2019, month=10, day=27, hour=1, minute=55).astimezone(timezone('UTC'))

i = 0
while i<10:
    x = x + timedelta(minutes=1)
    print(x.astimezone(timezone('Europe/London')))
    i+=1

2019-10-27 01:56:00-00:01
2019-10-27 01:57:00-00:01
2019-10-27 01:58:00-00:01

from datetime import datetime, timedelta
from pytz import timezone

x = datetime(year=2019, month=10, day=27, hour=1, minute=55).astimezone(timezone('UTC'))

i = 0
while i<10:
    x = x + timedelta(minutes=1)
    print(x.astimezone(timezone('Europe/London')))
    i+=1
