Python第四次作业

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

start_day = datetime(2019, 4, 1)
end_day = datetime(2019, 4, 30)

print("\t\t2019年4月")
print("星期一 星期二 星期三  星期四  星期五  星期六  星期天")

day = end_day - start_day  # 总天数
month = start_day.month    #月份
first = start_day.weekday()        # 第一天是星期几
day = day.days + 1                 # 所求月份的天数

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

f = 1
while f <= day:           # 判断天数
    print(f, end="\t")
    f += 1
    count += 1
    if (count % 7 == 0):  # 每七天换行
        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 = {"一个","我们","那里","如今","说道","知道","起来","这里","出来","他们","众人",
            "自己","没有","听见","怎么","什么","咱们","告诉","一面","东西","平儿","袭人","回来",
            "只是","只见","老爷","大家","只得","丫头","这些","不敢","出去","所以","不过",}
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 == "林黛玉"or word == "颦颦"or word == "颦儿":
        rword = "潇湘妃子"
    elif word == "贾宝玉" or word == "绛洞花主"or word == "富贵闲人"or word == "怡红公子":
        rword = "宝二爷"
    elif word == "薛宝钗" or word == "宝钗"or word == "宝姐姐" or word=="薛大姑娘":
        rword = "蘅芜君"
    elif word == "贾琏" or word == "琏二爷":
        rword = "二爷"
    elif word == "王熙凤" or word == "凤姐"or word == "凤姐儿"or word == "凤哥儿"or word == "醋坛子":
        rword = "琏二奶奶"
    elif word == "秦可卿"or word == "可卿":
        rword = "兼美"
    elif word == "贾母" or word == "老太太"or word == "老祖宗"or word == "老神仙":
        rword = "史太君"
    elif word == "贾惜春" or word == "惜春":
        rword = "惜春"
    elif word == "史湘云" or word == "史大姑娘"or word == "湘云" or word=="云妹妹":
        rword = "枕霞旧友"
    elif word == "芙蓉仙子" or word == "病西施":
        rword = "晴雯"
    elif word == "探春" or word == "贾探春"or word == "三姑娘":
        rword = "玫瑰花"
    elif word == "芳 官" or word == "耶律雄奴":
        rword = "金星玻璃"
    elif word =="柳湘莲":
        rword ="冷二郎"
    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
