Python's approach to automatically replacing IP

This article mainly introduces Python implementation of automatic replacement of IP methods, involving Python for the local network configuration of the relevant operational skills, very practical value, the need for friends can refer to the

This article is an example of how Python implements automatic replacement of IP. Share to everyone for your reference. The implementation methods are as follows:
