Python给出了时间增量数据的.seconds属性的错误结果

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给出了错误的值？

Answer 1

您只需要请求seconds的timedelta -您需要timedelta.total_seconds()方法。

timedelta.seconds属性只报告增量的最后一天的秒数。

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
