python 日期时间处理

datetime 转字符串

create_on.strftime('%Y-%m-%d %H:%M:%S')

字符串转datetime

collect_on = datetime.datetime.strptime(collect_on_str, '%Y%m%d%H%M%S')

datetime转时间戳

time.mktime(create_on.timetuple())

时间戳转datetime

req_datetime = datetime.datetime.fromtimestamp(timestamp)

计算时间差

time_delta = (collect_on - interval_datetime).seconds

时间差转datetime

interval_group_end = interval_group_start + datetime.timedelta(seconds=duration)
