Python 第四次作业叶炜

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 *
qishiri = datetime(2019, 4, 1)
yuewei = datetime(2019, 4, 30)
cha = yuewei - qishiri  # 所求月份天数天数
yuefen = qishiri.month  # 要打印的月份
first = qishiri.weekday()  # 所求月份的第一天是星期几
tianshu = cha.days + 1  # 所求月份的天数

count = 0
x = 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 x <= first:  
    x += 1
    print("    \t", end="")
    count += 1
    if (count % 7 == 0):
        print(" \n")

m = 1
while m <= tianshu:  # 循环几次与本月天数比较
    print(m, "\t", end="")
    m += 1
    count += 1
    if (count % 7 == 0):
        print("\n")  # 每七天进行换行

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 = {"什么","一个","我们","你们","如今","说道","知道","他们","自己","姑娘","起来","出来","只见","怎么","薛姨妈","所以","的话","不好",
            "没有","不是","不知","这样","进来","咱们","告诉","东西","听见","老爷","丫头","两个","这个","就是","平儿","众人","那里","心里"
            ,"这里","太太","回来","只是","大家","只得","这些","不敢","出去","一面","奶奶","不过","袭人","鸳鸯","一时","不能","过来","二人"
             ,"只管","这么","答应","今日","答应","几个","姐姐","王夫人","如此","银子","罢了","今儿","屋里","外头","打发","还有","这话","自然"

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 =="迎春"or word == "贾迎春":
        rword ="贾迎春"
    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(20): #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
