python中时间差中seconds和total_seconds

python中时间差中seconds和total_seconds - 折翼的飞鸟 - 博客园 (cnblogs.com)

都是获取两个datetime之间相差的秒数；

不同是的seconds不管日期，只计算时间之差，即时日期不同也只计算时间之差

total_seconds()计算的差值包括日期，也就是日期和时间之差

import datetime

t1 = datetime.datetime.strptime("2023-10-31 10:30:00", "%Y-%m-%d %H:%M:%S")
t2 = datetime.datetime.strptime("2023-10-31 12:30:00", "%Y-%m-%d %H:%M:%S")

interval_time = (t2 - t1).seconds
print(interval_time)  # 7200
total_interval_time = (t2 - t1).total_seconds()
print(total_interval_time)  # 7200.0

# 换一个方式
t1 = datetime.datetime.strptime("2023-10-27 10:30:00", "%Y-%m-%d %H:%M:%S")
t2 = datetime.datetime.strptime("2023-10-31 12:30:00", "%Y-%m-%d %H:%M:%S")
interval_time2 = (t2 - t1).seconds
print(interval_time2)  # 7200
total_interval_time2 = (t2 - t1).total_seconds()
print(total_interval_time2)  # 352800.0
