Python global variable release?

Question

Global variables need to be used in the project to store a large amount of data. This project will generally not be stopped, so this part will not be recycled. I have been tracking it for a while now, and I feel that this part of the memory is occupied, which greatly affects subsequent operations.
So I'm wondering if there is one that can be released at every point in time.

Answer 1

Depending on the situation, it will be deleted directly at the critical moment.

Answer 2

Del when you are not using it, and then in production, a good way is to use redis storage
