第四次作业--何仁喜

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 *
start_day = datetime(2019, 4, 1)
end_day = datetime(2019, 4, 30)
day = end_day - start_day  
month = start_day.month 
fist = start_day.weekday()  
day = d.days + 1  
count = 0
n = 1
print("\t\t2019年4月")
print("周一\t周二\t周三\t周四\t周五\t周六\t周日")
while n <= fist: 
    n += 1
    print("\t", end="")
    count += 1
    if (count % 7 == 0):
        print("\n")
m = 1
while m <= day: 
    print(m, "\t", end="")
    m += 1
    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。

import jieba
excludes = {"我们","什么","一个","那里","如今","说道","知道","你们","丫头","鸳鸯","不过",
            "起来","姑娘","这里","他们","众人","自己","一面","太太","只见","只得","一时",
            "奶奶","两个","出来","怎么","没有","不是","不知","这个","听见","这样","银子",
           "进来","咱们","告诉","就是","东西","袭人","回来","只是","大家","老爷","如此",
           "不敢","出去","所以","平儿","不好","姐姐","过来","这些","的话","不能","心里",}
txt = open("红楼梦.txt", "r", encoding='utf-8').read()
words  = jieba.lcut(txt)#精确模式的分词函数，返回一个列表数据类型
#print(type(words)) #words的数据类型
counts = {}  #定义一个字典
for word in words:
    if len(word) == 1:
        continue
    elif word == "宝玉" or word =="怡红公子"or word=="无事忙":
        rword = "贾宝玉"
    elif word == "黛玉" or word == "颦颦" or word == "颦儿" or word=="潇湘妃子" or word=="林姑娘" or word=="林妹妹":
        rword = "林黛玉"
    elif word == "凤姐" or word == "凤辣子"or word=="凤哥儿" or word=="凤姐儿":
        rword = "王熙凤"
    elif word == "贾母" or word == "老太太":
        rword = "贾母"
    elif word == "宝钗" or word == "宝姐姐" or word == "宝丫头" or word == "宝姑娘":
        rword = "薛宝钗"
    elif word == "贾琏":
        rword = "贾琏"
    elif word == "薛姨妈":
        rword = "薛姨妈"
    else:
        rword = word
    counts[rword] = counts.get(rword,0) + 1 #词汇加入字典
for word in excludes:
    del(counts[word])  #从字典中删除无用词
items = list(counts.items())#字典转换为列表

#lambda是一个隐函数，是固定写法，以下命令的意思就是按照记录的第2列排序  
"""x表示列表中的一个元素，x只是临时起的一个名字，
你可以使用任意的名字"""
items.sort(key=lambda x:x[1], reverse=True) 

for i in range(10): #出现的词频统计
    word, count = items[i] #将键和值分别赋予列表word和count
    print ("{0:<10}{1:>5}".format(word, count))#0:<10左对齐，宽度10，”>5"右对齐
