python - Python 使用 timedelta 数据的 .seconds 属性给出错误结果

Question

>>>print(today - date, (today - date).seconds)

[1] 63 days, 8:45:34.250649 31534
                              ↑

这与正确的结果相去甚远。31534 秒远小于 63 天。为什么 python 给出错误的值？

您只是请求-seconds您timedelta需要.timedelta.totalseconds()

timedelta.seconds唯一报告增量最后一天花费的所有秒数。

https://docs.python.org/3/library/datetime.html#datetime.timedelta.total_seconds

import datetime

d1 = datetime.datetime.now()

d2 = datetime.datetime.now()-datetime.timedelta(days=1.4)

delta = d1-d2

print(delta, delta.seconds, delta.total_seconds(), sep="\n")

输出：

1 day, 9:35:59.999997
34559  # (9 * 60 + 35 ) * 60 + 59 ca. 34559 - the full day is not part of ".seconds" 
120959.999997
