commands模块 subprocess模块 总结 §01 WindowsCmd命令 在Python程序中,经常需要调用Windows的命令,比如ipconfig、copy等等。 1.1 python的os模块 os模块调用CMD命令有两种方式:os.popen(),os.system()都是用当前进程来调用。 1.1.1 s.system os.system是无法获取返回值的。当运行结束后接着往下面...

ifp.returncode !=0: print"Error." return-1 3. 使用commands.getstatusoutput方法 这个方法也不会打印出cmd在linux上执行的信息。这个方法唯一的优点是,它不是一个阻塞的方法。即没有Popen函数阻塞的问题。使用前需要import commands。 例如: status, output = commands.getstatusoutput("ls") 还有只获得output...
