制作年历，无需导入日历

Question

编写一个给定的函数：

1. 一年

2. 一周中的某一天。

函数应该打印该年的年度日历

示例：

也可以考虑闰年。一年可以被4整除，但不能被100整除，这就是闰年！但如果能被400整除，那就是闰年了。 1900可以被4和100整除，但不是闰年。 2000年可被4和100“及400”整除，是闰年。

在制作这个日历时考虑闰年。

Answer 1

我想这差不多就可以了。

# List of tuples for Months and date ranges
# + 1 added to avoid confusion of max day range
