各位大神，小弟刚学写脚本不久，现在碰都一个问需要麻烦一下各位，大概逻辑流程是这样的：
下面的这段代码读取Excep表格中的IP地址、端口、用户名和密码通过SSH方式进入到网络交换机中，用python发送一些交换机的指令，通过这些指令把交换机中的配置文件(字符串的形式)输出到电脑上以.txt的格式保存并生成新的文件。
问题：输出的配置文件中上下行的间距有空格和#号，我想把行与行之间的空格和#号去掉，就先去除一下空格，调用了config = config.replace()这个命令，却发现没有效果依旧有空格，代码如下所示：该代码config = config.replace()命令被注释了。
求各位大神看下为何空格不能去掉呢，谢谢了。

Excel表格如下：
