设计题1：
设计一个本月份日历，输出格式如下：
要求：
1.初始化start_day，end_day两个日期
from datetime import datetime
start_day=datetime(2019,4,1)
end_day=datetime(2019,4,30)
其它时间数据生成要用datetime或date模块的方法编程实现
2.不能使用calendar模块生成
from datetime import datetime start_day = datetime(2019, 4, 1) end_day = datetime(2019, 4, 30) j=end_day-start_day week = start_day.weekday() day=j.days+ 1 count = 0 n = 1 print("2019年\n4月") print("星期一 星期二 星期三 星期四 星期五 星期六 星期天") while n<=week:n+=1print("\t", end="") d=1 while d<=day: print(d,end="\t")d+=1count+=1if (count%7==0):print("\n")
设计题2：
1.参考“三国演义”词频统计程序，实现对红楼梦出场人物的频次统计。
2.（可选）
将红楼梦出场人物的频次统计结果用词云显示。
