Python3 Exercise-Send IP address to mailbox

Requirements: Access the intranet via VPN from the extranet and log in to Computer A. Computer A through the shared folder (need \\IP access) to the intranet computer B, because the computer B's WI-fi IP address will change, so when computer B's I access path needs to know Computer B's latest IP

Ps:

1, only the basic functions of implementation, code is not standardized

2, to be modified to increase the log record, the configuration file is written to Sqllite

3, the method needs to be reconstructed, not flexible
