第四次作业

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
startday=datetime(2019,4,1)
endday=datetime(2019,4,30)
count = 0
print("2019年四月\n")
print("周一\t周二\t周三\t周四\t周五\t周六\t周日")
for i in range (0,30):
i=i+1
print(i,end="\t")
count=count+1
if count%7==0:
print("\n")

　　

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。
