您还可以通过使用datetime.datetime()函数 ➌ 来检索某个特定时刻的datetime对象,向其传递表示年、月、日、时和您想要的时刻的整数。这些整数将存储在datetime对象的year、month、day、hour、minute、属性中 ➍。 可以用datetime.datetime.fromtimestamp()函数将 Unix 纪元时间
datetime_object = datetime.today() The above code will populate the datetime_object variable with an object referencing the date and time right now. If we print datetime_object, you should see something similar to this:2018-03-11 13:12:03.572480 To format this datetime, we need to use mask...

1.2 datetime格式化输入输出 date, datetime, and time 类都支持通过 strftime(format) 方法来创建一个格式化的字符串来表示时间。strftime(“时间字符串”,format) 将格式时间字符串转换为datetime对象 反过来, datetime.strptime() 方法能够通过解释格式化的时间字符串创建一个 datetime 类实列。strptime(“时间字符串”...
