What are some examples of memory leaks in Python?

Memory leaks in Python can occur when objects are not properly released. For example, if you create a circular reference between two objects, they may not be garbage collected.

Can you give me a specific code example?

Sure! Here's a simple example:

class Node:
    def __init__(self, value):
        self.value = value
        self.next = None

node1 = Node(1)
node2 = Node(2)
node1.next = node2
node2.next = node1  # Circular reference

In this case, node1 and node2 reference each other, preventing garbage collection.

How can I avoid memory leaks in my Python code?

To avoid memory leaks, ensure that you break circular references and use weak references when necessary. Also, regularly monitor memory usage with tools like objgraph.

Are there any libraries that can help with memory management?

Yes, libraries like gc (garbage collector) can help manage memory. You can use it to manually trigger garbage collection or inspect objects.
