What is garbage collection in Python?
Garbage collection in Python is a mechanism for automatic memory management. It helps reclaim memory by removing objects that are no longer in use.
How does Python's garbage collection work?
Python primarily uses reference counting to track object usage. When an object's reference count drops to zero, it is immediately deallocated. Additionally, Python has a cyclic garbage collector to handle reference cycles.
What are reference cycles?
Reference cycles occur when two or more objects reference each other, preventing their reference counts from reaching zero. The cyclic garbage collector identifies and cleans up these cycles.
Can I control garbage collection in Python?
Yes, you can control garbage collection using the gc
module. You can enable or disable it, and manually trigger garbage collection if needed.
