Challenge Problems
Push your limits with advanced challenges
Design a small program that creates several data structures, measures their memory usage, modifies them, and then calculate the memory before and after calling gc.collect(). Discuss your findings.
💡 Hint: Focus on the relationship between object modifications and memory management.
Create a cyclic reference scenario where two objects reference each other. Use gc to demonstrate how they can be collected when no external references exist.
💡 Hint: Investigate how Python's garbage collector handles these circular dependencies.
