Python综合实战-股票数据分析&处理(查询接口）

开发程序对stock_data.txt进⾏行行以下操作：

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. 允许⽤用户通过模糊查询股票名，⽐比如输⼊入“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、换⼿手率这⼏几列列来筛选信息，⽐比如输⼊入“价格>50”则把价格⼤大于50的股票
   都打印，输⼊入“市盈率<50“，则把市盈率⼩小于50的股票都打印，不不⽤用判断等于。
   思路路提示：加载⽂文件内容到内存，转成dict or list结构，然后对dict or list 进⾏行行查询等操作。 这样以后
   就不不⽤用每查⼀一次就要打开⼀一次⽂文件了了，效率会⾼高

list_data=[]
#用来判断该列字符串最后一位是不是不是数字。
q_list=[4,5,6,8,10]
#用于处理两列单位不一致的
d_list=[7,11]
#将数据转化成一个列表
