作业1

每个人针对之前两次作业所写的代码，针对要求，并按照代码规范（风格规范、设计规范）要求评判其他学生的程序，同时进行代码复审（按照代码复审核表）
评价内容直接放在你被评价的作业后面评论中
同时另建立一个博客，将你作的评论的截图或者链接，放在博客中，并在你的博客中谈谈自己的总体看法

作业2

1、实现一个简单而完整的软件工具（中文文本文件人物统计程序）：针对小说《红楼梦》要求能分析得出各个人物在每一个章回中各自出现的次数，将这些统计结果能写入到一个csv格式的文件。
2、进行单元测试、回归测试、效能测试，在实现上述程序的过程中使用相关的工具。
3、进行个人软件过程（PSP）的实践，逐步记录自己在每个软件工程环节花费的时间。
4、使用源代码管理系统 (GitHub, Gitee， Coding.net, 等)；
5、针对上述形成的软件程序，对于新的文本小说《水浒传》分析各个章节人物出现次数，来考察代码。
将上述程序开发结对编程过程记录到新的博客中，尤其是需要通过各种形式展现结对编程过程，并将程序获得的《红楼梦》与《水浒传》各个章节人物出现次数与全本人物出现总次数，通过柱状图、饼图、表格等形式展现。
《红楼梦》与《水浒传》的文本小说将会发到群里。
注意，要求能够分章节自动获得人物出现次数

python准备工作

先下载python，并安装好所需要的模块——jieba和matplotlib

python运行结果（红楼梦）

在python中按题目要求先将出现的高频词汇去除，再统计出红楼梦和水浒传人物出现的次数，并导入到csv文件中。

PSP

PSP各个阶段	预估时间	实际记录
计划：明确需求和其他因素，估计以下的各个任务需要多少时间	一小时	一天
开发
需求分析	一小时	三小时
生成设计文档	一小时	一小时
具体代码	五小时	五小时
测试	一小时	两小时
事后总结	两小时	两小时
总共花费的时间	十一小时	两天

#红楼梦人物出现次数导入csv
#导入csv安装包
import csv

#1、创建文件对象
with open('HLMcsv.csv','w',newline="") as csvfile:

#2、基于文件对象构建csv写入对象
    writer=csv.writer(csvfile)

#3、构建列表头
    writer.writerow(["人物","出现次数"])

#4、写入csv文件内容
    writer.writerow(["宝玉","3445"])
    writer.writerow(["贾母","1144"])
    writer.writerow(["凤姐","1038"])
    writer.writerow(["王夫人","969"])
