今天和大家分享一下python如何读取txt文件内容并进行数据分析的
需求:某txt文件中存在很多数据,这些数据的某一个属性主要分为A、B、C、D四类，要求把数据分成四类求某一数值属性的平均值，并统计生成超过平均值两倍或者三倍的数据。打包成exe应用程序。

一、实现思路
二、代码展示
三、总结
一、实现思路
1、读取文件，获取文件的每一行数据
2、分析文件数据，返回其独特的分割方法(这里我的txt文件是以制表符分割)
3、因为readlines读出来之后是列表形式，所以我们可以利用索引取我们想要的数据
4、根据需求设定判断条件
5、满足条件的数据重新写入某一个。txt文件里面
6、要平均值我们就加平均值
7、要打印我们就加打印
8、还要统计报表我们就根据需求再创建.txt文件进行追加
9、加入我们的input，try except进行优化
10、pyinstaller打包
11、成功
二、代码展示
"""
调度统计
是需要把算法文件中的PassiveReplan ActiveReplan DeadLockReplan SolDeadLock 数据分为4类，
再分别将这4类的perTskNum求平均值,再生成超过平均值x倍的数据,合成一个统计报表，最后剔除查过平均值x倍的数据求平均值。

三、总结
此代码最为练手使用，其中运用了文件读写，数据类型的转换、数据索引等知识点。最后为了方便使用打包成.exe应用程序 打包命令：
pyinstall -F XXX.py
