🧠 Quiz: What is the most "Pythonic" way to create a new list containing the squares of numbers from an existing list called nums?

A) Using a for loop and the .append() method.
B) new_list = [num**2 for num in nums]
C) Using a while loop with an index counter.
D) new_list = (num**2 for num in nums)

Correct answer: B

Explanation: This is a list comprehension. It's a concise, readable, and often faster way to create a new list from an iterable compared to a traditional for loop. Option D creates a generator expression, not a list.
