最后,我们可以使用datetime对象的year属性来提取年份。 year=now.year 1. 在这个例子中,我们使用了datetime对象的year属性,并将其赋值给了一个变量year。 现在,我们可以将这些步骤整合到一起,并编写一个完整的代码示例: importdatetime now=datetime.datetime.now()year=now.yearprint("当前年份:",year) 1. 2. ...

datetime类是date和time的结合体,包括date与time的所有信息,date和time类中具有的方法和属性,datetime类都具有。 所以在我们日常的工作中,可以仅使用datetime类。该类的构造函数: datetime.datetime(year, month, day[, hour[, minute[, second[, microsecond[,tzinfo]]]) 各参数的含义与date、time构造函数中的一...
