How does the Garbage Collector free memory inside objects?

In Python, the garbage collector (Garbage Collector) frees memory using two main mechanisms:

1. Reference counting: each object keeps track of the number of references to it. When the reference count of an object becomes zero, the memory occupied by the object is released.

2. Cyclic garbage collector: to detect and remove cyclic references that cannot be freed by reference counting, an algorithm traverses objects and identifies cycles, after which the memory is freed.

Thus, the Garbage Collector automatically manages memory by freeing objects that are no longer referenced or are part of cycles without external references.
