Python日历模块：HTMLCalendar formatyearpage() 方法
日历模块允许像程序一样输出日历，并提供与日历相关的附加有用功能。 Calendar 模块中定义的函数和类使用理想化的日历，当前的公历在两个方向上无限扩展。
class calendar.HTMLCalendar(firstweekday=0)可用于生成 HTML 日历。 formatyearpage() 方法是 HTMLCalendar 实例的方法之一。
Python中的formatyearpage()方法用于将年份的日历获取为完整的 HTML 页面。
Syntax: formatyearpage(year, width=3, css=’calendar.css’, encoding=None)
Parameter:
year: year of the calendar
width:[Default value is 3] Specifies the width date column
css: [Optional] Name for the CSS to be used.
encoding: [Optional] Specifies the encoding to be used for output
Returns: Return an HTML page for an entire year.
取决于构造函数中指定的或由setfirstweekday()方法设置的第一个工作日。

# Python program to demonstrate working of formatyearpage() method
# importing calendar module
import calendar
text_cal = calendar.HTMLCalendar(firstweekday = 0)
year = 2018
# Default value of width is 3
# printing formatyearpage
print(text_cal.formatyearpage(year))
