python第四次作业——曾景

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)
days= end_day - start_day

month = start_day.month
week = start_day.weekday()
day = days.days + 1
count = 0
i= 0
print("4月 2019")
print("-----------------------------------------------------")
l = ("星期一", "星期二", "星期三", "星期四", "星期五", "星期六", "星期日")
for n in l:
print(format(n, "4"), end=" ")

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

p = 1
while p <= day:
print(p, "\t", end="")
p += 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。

words = jieba.lcut(txt)
 
counts = {}   # 定义一个字典
 
for word in words:
    if len(word) == 1:
        continue
    elif word == "宝玉":
        rword = "贾宝玉"
    elif word == "黛玉":
        rword = "林黛玉"

    elif word == "探春":
        rword = "贾探春"
    elif word == "晴雯":
        rword = "晴雯"
    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(11):   # 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:<7}".format(word, count))   # 0:<10左对齐，宽度10，”>5"右对齐
