我们可以将该类加载到 Python 3 解释器中,这样我们就可以交互式地使用它。为了做到这一点,将前面提到的类定义保存在一个名为first_class.py的文件中,然后运行python -i first_class.py命令。-i参数告诉 Python运行代码然后转到交互式解释器。以下解释器会话演示了与这个类的基本交互:...

After importing the socket module, we instantiate a new variable s from the class socket class. Next, we use the connect() method to make a network connection to the IP address and port. Once successfully connected, we can read and write from the socket. The recv(1024) method will read...
导语 生产环境中使用paramiko作SSH远程控制时,发现会有部分机器报Error reading SSH protocol banner错误,尝试使用ssh命令连接此机器,只是卡半天,最终还是能够正常登陆。 最近一直做运维发布平台,底层命令行、文件通道主要基于paramiko模块,使用过程中遇到各种各样的问题,本文主要用于收集问题及解决记录,以备后续使用。
