How can I use objgraph for memory profiling in Python?

You can use objgraph to visualize Python object graphs and identify memory leaks. Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

import objgraph

# Create some objects
class MyClass:
    pass

obj1 = MyClass()
obj2 = MyClass()

# Generate a reference cycle
obj1.ref = obj2
obj2.ref = obj1

# Show the object graph
objgraph.show_backrefs([obj1], max_depth=3)

This will help you visualize the references between objects.

What should I look for in the output?

Look for unexpected references that may indicate memory leaks, such as objects that should have been garbage collected but are still referenced.
