【Python作业】对股票数据分析&处理

文章目录

一、前言

上午写了一个版本，将简单问题复杂化了，本题主要考的是 文件操作及常见数据类型的处理 ，惭愧学了几个月基础还是很差，想想还是觉得不对劲，重新写了一个版本，精简不少。

版本1：Python综合实战对股票数据分析&处理

二、 题目要求

开发程序对stock_data.txt进行以下操作：

1. 程序启动后，给⽤用户提供查询接⼝口，允许⽤用户重复查股票⾏行行情信息(⽤用到循环)
2. 允许用户通过模糊查询股票名，⽐如输入“啤酒”, 就把所有股票名称中包含“啤酒”的信息打印出来
3. 允许按股票价格、涨跌幅、换手率这⼏列来筛选信息，⽐如输入“价格>50”则把价格大于50的股票都打印，输⼊入“市盈率<50“，则把市盈率小于50的股票都打印，不用判断等于。

思路提示：加载⽂件内容到内存，转成dict or list结构，然后对dict or list
进行查询等操作。这样以后就不用每查一次就要打开一次文件了，效率会高。
