Notes when using rpclib for Python Network ProgrammingThis article mainly introduces the annotation problem when using rpclib for Python network programming. The author tells me that he needs to pay attention to unicode annotations when writing servers. For more information,

This article mainly introduces the Python Simple Network programming, details the client and the service side of the specific implementation skills and related considerations, the need for friends can refer to the following The examples in this article describe Python's Simple network
