第四次python作业——檀健勇
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
