注意:os.popen() 方法用于从一个命令打开一个管道。在Unix,Windows中有效 实例 1.前面对os.popen的方法有了初步了了解了,接下来就运用到实际操作中吧! 在app自动化的时候,经常用到指令:adb devices来判断是否连上了手机,那么问题来了,如何用python代码判断是否正常连上手机?
os.system(command)返回命令执行状态码,而将命令执行结果输出到屏幕; os.popen(command).read() 可以获取命令执行结果,但是无法获取命令执行状态码; commands.getstatusoutput(command) 返回一个元组(命令执行状态码, 命令执行结果); os.popen(command)函数得到的是一个文件对象,因此除了read()方法外还支持write()等...
