# 先获得时间数组格式的日期 threeDayAgo = ( datetime . datetime . now ( ) - datetime . timedelta ( days = 3 ) ) # 转换为时间戳 timeStamp = int ( time . mktime ( threeDayAgo . timetuple ( ) ) ) # 转换为其他字符串格式 otherStyleTime = threeDayAgo . strftime ( " %Y-%m-%d %H:%M:%S " ) print ( otherStyleTime )

执行以上代码输出结果为:

2019-05-18 18:06:08 #给定时间戳 timeStamp = 1557502800 dateArray = datetime . datetime . utcfromtimestamp ( timeStamp ) threeDayAgo = dateArray - datetime . timedelta ( days = 3 ) print ( threeDayAgo )

执行以上代码输出结果为:

2019-05-07 15:40:00
