第4次Python作业——沈朝铨

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 *
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 = 0
count = 0
print("\t\t\t2019年4月")
print("星期日 星期一 星期二 星期三 星期四 星期五 星期六")
while k<=first:
    k+=1
    count+=1
    print("\t", end="")
 
day = 1
while day <= amount:
    print(day, end="\t")
    day += 1
    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。

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(7): #出现的词频统计
    word, count = items[i] #将键和值分别赋予列表word和countf
    print ("{0:<10}{1:>5}".format(word, count))#0:<10左对齐，宽度10，”>5"右对
