第四次作业——吕智超

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)
count=0
print("\t\t\t\t2019年4月 ")
print("星期一\t\t星期二\t\t星期三\t\t星期\t\t星期五\t\t星期六\t\t星期天")
for i in range (0,30):
    i=i+1
    print(i,end="\t\t")
    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

 2 excludes = {"什么","一个","我们","那里","你们","如今","说道","知道","起来","这里","出来","他们","众人","自己",
 3             "奶奶","一面","只见","怎么","姑娘","两个","没有","不是","不知","这个","听见","这样","进来","这是",
 4             "告诉","就是","咱们","东西","回来","只是","大家","老爷","只得","丫头","这些","不敢","出去","所以",
 5             "不过","的话","不好","姐姐"}
 6 txt = open("红楼梦.txt", "r", encoding='utf8').read() #打开文件并定义
