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 timedelta

from datetime import *

start_day = datetime(2019, 4, 1)

end_day = datetime(2019, 4,30)

a=end_day-start_day

amount = a.days + 1

first=start_day.isoweekday()

k = 1

count=0

print("\t\t\t2019年4月")

print("星期一  星期二  星期三  星期四  星期五  星期六  星期日")

while k < first:

k=k+1

print("\t", end="   ")

p = 1

while p <= amount:

print(p, "\t", end="   ")

p =p+1

count =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 = {"什么","一个","我们","那里","你们","如今","说道","起来","姑娘","这里","出来","他们","众人","自己",

"一面","只见","太太","奶奶","两个","没有","不知","这个","听见","这样","进来","咱们","告诉","怎么",

"就是","东西","回来","只是","老爷","大家","东西","只见","只得","所以","的话","不好","姐姐","不是",

"鸳鸯","知道","丫头"}

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 == "贾宝玉" or word == "宝玉"or word=="二爷":

rword = "贾宝玉"

elif word == "黛玉" or word == "颦儿" or word=="潇湘妃子"  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=="凤丫头" :

rword = "王熙凤"

elif word == "贾母" or word == "老太太":

rword = "贾母"

elif word == "宝钗" or word == "蘅芜君"or word == "宝姐姐" or word == "宝丫头" or word == "宝姑娘":

rword = "薛宝钗"

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(9): #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
