In which scenarios in Python should you use the garbage collector module?

The gc module in Python should be used in the following scenarios:

• When there are cyclic references between objects in the program that are not automatically freed by reference counting. The gc module helps detect and clean up such cycles.
• For debugging and monitoring the garbage collector: you can enable logging, view the number of objects that were not collected.
• In cases where you need to explicitly control garbage collection, for example, calling gc.collect() at a specific moment to free memory.

Example of usage:

import gc

# Enable automatic garbage collection
gc.enable()

# Force a garbage collection
collected = gc.collect()
print(f"Objects collected: {collected}")

# Get a list of objects that were not collected
unreachable = gc.garbage
print(f"Objects not collected by GC: {unreachable}")

Usually, in standard Python programs, you do not need to directly use gc, as garbage collection works automatically. But when working with large data volumes, complex structures, or debugging memory leaks, the gc module is very useful.
