Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What does the sys.getsizeof() function return?

  • The number of references to an object
  • The total memory used by the Python interpreter
  • The memory size in bytes of an object

💡 Hint: Focus on what 'size' implies.

Question 2

True or False: The gc module can be used to manually trigger garbage collection.

  • True
  • False

💡 Hint: Think about how you control cleaning up unused objects.

Challenge Problems

Push your limits with challenges.

Question 1

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.

Question 2

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.
