我们在压力测试过程会收集到很多log，怎样快速从中找到有用信息呢？让python脚本帮我们做这部分工作吧！
废话不说，上代码
环境：win10 + python2.7.14

关键字及被扫描的日志路径信息，记录到文件中，以逗号+空格隔开，如，“， ”日志路径信息放到最后。
格式如下：
|
1
|
anr, dalvikvm: could not find class 'android.app.usage., panic, c:\users\bhj\logcat1.log
|
执行结果：
以上这篇python实现扫描日志关键字的示例就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持服务器之家。
