# Explain Python’s garbage collection mechanism.

Python uses **reference counting** and **a cyclic garbage collector**.

- When an object’s reference count becomes zero, it’s automatically destroyed.
- The **gc module** handles circular references.

```python
import gc
gc.collect()  # manually trigger garbage collection
```
