	        // TODO Auto-generated method stub
	        String pwdString = exec("pwd").toString();
	        String netsString = exec("netstat -nat|grep -i \"80\"|wc -l").toString();----------------------- 我这里拿来执行python文件的，这里赋值 是python里面return回来的值 ---print的不会返回回来
	         
	        System.out.println("==========获得值=============");
	        System.out.println(pwdString);
	        System.out.println(netsString);
	    }
	 
	}
