Welcome to your interview.
The question is on your right: Generator vs List Comprehension. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
What is the difference between a generator and a list comprehension in Python in terms of memory utilization and execution? When would you choose one over the other?
