将开始时间和结束时间之间的差值转换为小时。分钟和秒

import datetime

def time_difference(start_time, end_time):
    start_timestamp = datetime.datetime.strptime(start_time, "%Y-%m-%d %H:%M:%S").timestamp()
    end_timestamp = datetime.datetime.strptime(end_time, "%Y-%m-%d %H:%M:%S").timestamp()
    diff_seconds = int(end_timestamp - start_timestamp)
    hours = diff_seconds // 3600
    minutes = (diff_seconds % 3600) // 60
    seconds = (diff_seconds % 60)
    return hours, minutes, seconds

start_time = "2022-01-01 12:00:00"
end_time = "2022-01-01 15:30:45"

hours, minutes, seconds = time_difference(start_time, end_time)
print(f"差值为：{hours}小时{minutes}分钟{seconds}秒")
