Challenge Problems

Push your limits with challenges.

Question 1

You are tasked with writing a Python function that computes the total of all even numbers between 1 and 1,000,000. Compare the performance of a traditional loop using a list to a generator approach. Discuss your findings.

💡 Hint: Think about how much memory a full list of even numbers would use.

Question 2

Analyze a piece of code that uses global variables extensively. Refactor it to minimize global state. Then measure the performance and memory usage before and after the modification.

💡 Hint: Check how many times variables are being accessed in the original code.
