first_day_of_current_month=datetime.datetime(current_date.year,current_date.month,1)previous_month_end_date=first_day_of_current_month-datetime.timedelta(days=1) 1. 2. 最后,我们可以打印出获取到的上个月的起始日期和结束日期,代码如下所示:
如果是星期一,返回0;如果是星期2,返回1,以此类推;data.isoweekday():返回weekday,如果是星期一,返回1;如果是星期2,返回2,以此类推;date.isocalendar():返回格式如(year,month,day)的元组;date.isoformat():返回格式如'YYYY-MM-DD’的

Example: Get the year, month, day from the date object To extract the year, month and day from a date object, use the .year, .month, and .day attributes of the date class: from datetime import date current_date = date.today() year = current_date.year print("The year is: ", yea...

之后借助RequestHandler来作为输出响应函数,创建视图部分。 值得注意的是,request可以是get()或post()处理函数,如果想让子类支持其他的标准请求如GET/HEAD/POST等,可以在子类中覆盖这些方法; self.render()用于接收值渲染——接收self.render()方法传值的变量或一个值 ...
