第四次作业

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

 

from datetime import datetime
from datetime import timedelta

from datetime import *
start_day = datetime(2019, 4, 1)
end_day = datetime(2019, 4, 30)
a=end_day-start_day
amount = a.days + 1
first=start_day.isoweekday()
k = 1
count=0
print("\t\t\t2019年4月")
print("星期一 星期二 星期三 星期四 星期五 星期六 星期日")
while k < first:
    k=k+1
    print("\t", end="   ")
p = 1
while p <= amount:
    print(p, "\t", end="   ")
    p =p+1
    count =count+1
    if (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。
