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

month = start_day.month   # 要打印的月份
week = start_day.weekday()  # 4月的第一天是星期几
day = Dt.days + 1  # 4月的天数

count = 0
k = 0
print("\t\t2019年4月")
print("日\t一\t二\t三\t四\t五\t六")
while k <= week:   # 每个月的开始第一周前面的空格数
    k += 1
    print("\t", end="")

    if(count % 7 == 0):
        print("\n")        # count=7 进行换

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。
