第四次作业 （日期和jieba库的运用）

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
from datetime import timedeltastart_day = datetime(2019, 4, 1)
end_day = datetime(2019, 4, 30)
day = end_day - start_daymonth = start_day.month  #打印的月份
week = start_day.weekday()  #获取当月第一天是星期几
day_1 = day.days + 1  #4月的天数

count = 0
n = 0
print("\t\t 2019年4月")
print("日\t一\t二\t三\t四\t五\t六")#第一周前面的空格数
while n <= week:n += 1print("\t", end="")count += 1   #空格数也要算上，和下面的 count += 1 共同控制格式

d = 1
while d <= day_1:  #显示天数print(d, end="\t")d += 1count += 1if (count % 7 == 0):print("\n")  #count=7进行换行

运行结果：

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。
