Can the automatic memory management mechanism in Python delete objects that are important for the program?

The automatic memory management mechanism in Python is based on reference counting and a garbage collector for cyclic references. It deletes objects that are no longer referenced in the program, i.e., objects that are inaccessible.

It is important to note that Python does not delete objects that are still in use (have at least one reference). Therefore, objects that are important for the program will not be automatically deleted as long as there are references to them.

However, if all references to an object are mistakenly removed or the object becomes inaccessible (for example, due to a logical error), it may be deleted by the garbage collector, leading to data loss. But this is a bug in the code, not a problem with the memory management mechanism.
