Memory management in Python is a crucial aspect for developers, especially given Python’s widespread use in software development. Python employs automatic memory management, which means it allocates and deallocates memory as needed. This system primarily relies on two key components: reference counting and garbage collection.

Reference counting tracks how many references point to an object in memory. When the reference count drops to zero, Python automatically frees that memory. However, this method can struggle with cyclic references, where two or more objects reference each other, preventing their memory from being released. To address this, Python includes a garbage collector that detects and removes these cyclic references, ensuring efficient memory usage.

Understanding these mechanisms is essential for writing efficient and maintainable Python code. Poor memory management can lead to performance issues, such as slow applications and memory leaks, which can complicate testing and debugging processes ¹³⁴.
