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
1 from datetime import datetime 2 start_day=datetime(2019,4,1) 3 end_day=datetime(2019,4,30) 4 print(start_day.year,"年",start_day.month,"月") 5 print("星期一 星期二 星期三 星期四 星期五 星期六 星期天") 6 #返回日期是星期几，[1, 7], 1表示星期一 7 i=start_day.isoweekday() 8 j=0 9 count=0 10 while(i<1): 11 j=j+1 12 print("\t", end="") 13 count += 1 14 if (count % 7 == 0):#每计七个数进行换行 15 print("\n") 16 d=end_day - start_day 17 day=d.days 18 first=0 19 while(first<=day): 20 first=first+1 21 print(first,"\t", end=" ") 22 count += 1 23 if (count % 7 == 0):#每计七个数进行换行 24 print("\n")
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。
1 import jieba 2 txt = open("C:\\Users\\李雷\\红楼梦.txt", "r", encoding='utf8').read() 3 counts = {} #定义一个字典 4 for word in words: 5 if len(word) == 1: 6 continue 7 elif word == "宝玉" or word == "宝二爷" or word == "怡红公子" or word == "绛洞花主" or word == "无事忙" or word == "遮天大王" or word == "混世魔王" or word == "槛内人" or word == "浊玉": 8 rword = "贾宝玉" 9 elif word == "宝钗" or word == "蘅芜君" or word == "宝姐姐" or word == "宝丫头" or word == "宝姑娘": 10 rword = "薛宝钗" 11 elif word == "凤姐" or word == "琏二奶奶" or word=="凤辣子"or word=="凤哥儿"or word=="凤丫头" or word=="凤姐儿" or word == "熙凤道": 12 rword = "王熙凤" 13 elif word == "颦颦" or word == "颦儿" or word == "潇湘妃子" or word == "林姑娘" or word == "林妹妹" or word == "黛玉": 14 rword = "林黛玉" 15 elif word == "晴雯" or word == "勇晴雯" or word == "芙蓉仙子" or word == "病西施": 16 rword = "晴雯" 17 elif word == "老祖宗" or word == "老太太" or word == "史太君" or word == "贾母": 18 rword = "贾母" 19 else: 20 rword = word 21 counts[rword] = counts.get(rword,0) + 1 #词汇加入字典 22 for word in excludes: 23 del(counts[word]) #从字典中删除无用词 24 items = list(counts.items())#字典转换为列表 25 26 #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 27 """x表示列表中的一个元素，x只是临时起的一个名字， 28 你可以使用任意的名字""" 29 items.sort(key=lambda x:x[1], reverse=True) 30 31 for i in range(6): #出现的词频统计 32 word, count = items[i] #将键和值分别赋予列表word和countf 33 print ("{0:<10}{1:>5}".format(word, count))#0:<10左对齐，宽度10，”>5"右对齐
