Python implements 2 file replacement updates

Business requirements: Ansible synchronization, hosts need to be updated with changing zk-hosts files. And in the specified location to add and delete, in this case add and delete for [prod] this project.

Idea: Each [prod] square bracket begins with an item as a dictionary key, with the IP under it as a value. Make it into a dictionary. When updating, first go to the [] item name, then go to update its value, including delete, increase, determine whether there is.
