List Comprehensions vs Loops

What's the difference between list comprehensions and loops in Python?

List comprehensions provide a concise way to create lists. They can be more readable and faster than loops.

Can you give me an example of both?

Sure! For a loop: result = [] followed by for i in range(5): result.append(i * 2). For a list comprehension: result = [i * 2 for i in range(5)].

Which one is more efficient?

List comprehensions are generally more efficient than loops because they are optimized for performance in Python.

Are there any situations where loops are better?

Yes, loops can be better for complex operations or when readability is a concern, especially for beginners.
