第四次作业 ——吴靖瑜

习题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
代码：

from datetime import datetime
start_day=datetime(2019,4,1)
end_day=datetime(2019,4,30)
print(start_day.strftime('\t\t\t%Y/%m'))#输出年份与月份
print("星期日\t星期一\t星期二\t星期三\t星期四\t星期五\t星期六")
first_day=start_day.weekday()
day=30    #2019年4月有30天
count = 0    #定义一个计数器
k = 0
while k <= first_day:   #每个月的开始第一周前面的空格数
    k += 1
    print("  \t",end=" ")
    count += 1
    if (count % 7 == 0):print(" \n")   # count=7 进行换行
p = 1
while p <= day:    #显示天数
    print(p,"\t",end="")     #打印  table 不换行
    p += 1
    count += 1
    if(count % 7 == 0):print("\n")        #count=7 进行换行

习题2：

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。

 代码：

import jieba
excludes = {"怎么","快去","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","有些","说道","下来","不如","后来","里面","然后","一面","今儿",
            "自己","这么","这个","别处","东西","好看","舍得","远远","那里","这里",
            "各自","一边","一面","一个","只管","只觉","银子","俺们","咱们","回来","不能","天天"}
txt = open("红楼梦.txt", "r", encoding='utf-8').read()
words  = jieba.lcut(txt)
count = {} 
for word in words:
    if len(word) == 1:
        continue
    elif word == "宝哥哥" or word == "宝二爷"or word=="怡红公子"or word=="绛洞花王":

    elif word == "二姑娘" or word == "二木头" or word=="菱洲":
        rword = "贾迎春"
    elif word == "四姑娘" or word == "四丫头" or word=="藕榭" or word=="藕丫头":
        rword = "贾惜春"
    elif word == "秦氏" or word == "蓉大奶奶" or word=="可儿" or word=="兼美":
        rword = "秦可卿"
    else:
        rword = word
    count[rword] = count.get(rword,0)+1 
for word in excludes:
    del(count[word])
items = list(count.items())
items.sort(key=lambda x:x[1], reverse=True)
for i in range(25): 
    word, count= items[i] 
    print ("{0:<10}{1:>6}".format(word, count))
