Python 快速定制 Web 日历

通过重写python calendar模块的HTMLCalendar类可以快速的定制自己需要Web日历。需要改写的地方不多，替换一下原来的css就ok了，month_name，day_abbr 这两个函数注意改写一下。Tornado默认会自动转义模板中的内容，你可以使用{% raw %}指令来输出不转义的内容。

如：{% raw cal %}

import calendar
import datetime
class MyCalendar(calendar.HTMLCalendar):
    def lastmonth(self, theyear, themonth):
        '''上个月的最后一天'''
        first = datetime.date(day=1, month=themonth, year=theyear)
        lastMonth = first - datetime.timedelta(days=1)
        return lastMonth.strftime("/log/%Y-%m/-%d")
    def nextmonth(self, theyear, themonth):
        '''下个月的第一天'''
        last = datetime.date(day=calendar.mdays[themonth], month=themonth, year=theyear)
        nextMonth = last + datetime.timedelta(days=1)
        return nextMonth.strftime("/log/%Y-%m/-%d")

    def formatday(self, day, weekday):
        if day == 0:
            #加入td的css
            return ' ' # day outside month

            return '%d' % (day, day)

        else:

f.write(chunk)
f.close
