这篇文章主要介绍了Python datetime模块的使用示例，帮助大家更好的理解和使用python处理时间，感兴趣的朋友可以了解下
1、获取当前年月日时分秒
# -*- encoding=utf-8 -*- import datetime Now = datetime.datetime.Now() print("Now:{}".format(Now)) year = Now.year print("year:{}".format(year)) month = Now.month print("month:{}".format(month)) day = Now.day print("day:{}".format(day)) hour = Now.hour print("hour:{}".format(hour)) minute = Now.minute print("minute:{}".format(minute)) second = Now.second print("second:{}".format(second))
2、datetime转为string
# -*- encoding=utf-8 -*- import datetime Now = datetime.datetime.Now() print('type:{}'.format(type(Now))) print('Now datetime:{}'.format(Now)) Now_string = Now.strftime('%Y-%m-%d %H:%M:%s') print('type:{}'.format(type(Now_string))) print('Now string:{}'.format(Now_string))
3、string转为datetime
# -*- encoding=utf-8 -*- import datetime time_str = '2021-01-28 10:51:26' time_date = datetime.datetime.strptime(time_str, '%Y-%m-%d %H:%M:%s') print('type:{}'.format(type(time_date))) print(time_date)
4、时间相加
# -*- encoding=utf-8 -*- import datetime time_str = '2021-01-28 10:00:00' time_date = datetime.datetime.strptime(time_str, '%Y-%m-%d %H:%M:%s') print('原始时间:tttt{}'.format(time_date)) add_info = datetime.timedelta(days=1, hours=2, minutes=3, seconds=4) add_end = time_date + add_info print('加上1天2个小时3分钟4秒后:t{}'.format(add_end))
5、时间相减
①两个时间差
# -*- encoding=utf-8 -*- import datetime time_str = '2021-01-28 10:00:00' time_date = datetime.datetime.strptime(time_str, '%Y-%m-%d %H:%M:%s') print('原始时间:t{}'.format(time_date)) time_str = '2021-05-29 12:12:12' time_date2 = datetime.datetime.strptime(time_str, '%Y-%m-%d %H:%M:%s') print('原始时间2:t{}'.format(time_date2)) time_date3 = time_date2 - time_date print('时间差:{}'.format(time_date3))
②减去1天2个小时3分钟4秒（加负数）
# -*- encoding=utf-8 -*- import datetime time_str = '2021-01-28 10:00:00' time_date = datetime.datetime.strptime(time_str, '%Y-%m-%d %H:%M:%s') print('原始时间:tttt{}'.format(time_date)) add_info = datetime.timedelta(days=-1, hours=-2, minutes=-3, seconds=-4) add_end = time_date + add_info print('减去1天2个小时3分钟4秒后:t{}'.format(add_end))
