你好！我需要有关日期时间的帮助

Question

我写了这段代码：

chegada = input('Enter arrival time: "Hours: Minutes" ')
saida = input('Inform the time of departure: "Hours: Minutes" ')

fmt = '%H:%M'
tdelta = datetime.strptime(saida, fmt) - datetime.strptime(chegada, fmt)
if tdelta.days < 0:
    tdelta = timedelta(days=0, seconds=tdelta.seconds,
        microseconds=tdelta.microseconds)

现在我想知道如何在几秒钟内完成转换

Answer 1

from datetime import datetime
from datetime import timedelta

chegada = input('Enter arrival time: "Hours: Minutes" ')
saida = input('Inform the time of departure: "Hours: Minutes" ')

fmt = '%H:%M'
tdelta = datetime.strptime(saida, fmt) - datetime.strptime(chegada, fmt)
if tdelta.days < 0:
    tdelta = timedelta(days=0, seconds=tdelta.seconds,
        microseconds=tdelta.microseconds)
print(tdelta)
print(tdelta.total_seconds())
