20221328 2022-2023-2 《Python程序设计》实验一报告

课程：《Python程序设计》
班级： 2213
姓名： 马申明
学号：1328
实验教师：王志强
实验日期：2023年5月4日
必修/选修： 公选课

1.实验内容

Python综合应用：爬虫、数据处理、可视化、机器学习、神经网络、游戏、网络安全等。
课代表和各小组负责人收集作业（源代码、视频、综合实践报告）

例如：编写从社交网络爬取数据，实现可视化舆情监控或者情感分析。

例如：利用公开数据集，开展图像分类、恶意软件检测等

例如：利用Python库，基于OCR技术实现自动化提取图片中数据，并填入excel中。

例如：爬取天气数据，实现自动化微信提醒

例如：利用爬虫，实现自动化下载网站视频、文件等。

例如：编写小游戏：坦克大战、贪吃蛇、扫雷等等

注：在Windows/Linux系统上使用VIM、PDB、IDLE、Pycharm等工具编程实现。

实验过程：

• 1. 抄书；
• 2. 改代码，改变了柱子出现的高度，增加了随机数；
     增加了柱子数量；
     增加了分数；

遇到的问题及感想

• 问题一：上下柱子图片重叠；
• 解决方案：改坐标参数成功解决；
• 问题二：无法添加音乐；
• 解决方案：将所需模块复制到win64，未能解决；
• 问题三：小道具功能失效；

感想

想法未能成功转变成实际，难受；

总结

• 学会了基本的python语法；
• 了解了一些python术语；
• 做了四次实验；

  体会

• 课程紧了点
• 实操少了点
• 复习资料无
