What are the best practices for creating iterables in programming?

When creating iterables, consider using generator functions for memory efficiency, and ensure they are easy to iterate over.

Can you explain why generator functions are more memory efficient?

Generator functions yield items one at a time, which means they don't store the entire iterable in memory, reducing memory usage.

What about using list comprehensions? Are they a good practice?

Yes, list comprehensions are concise and can be more readable, but they load the entire list into memory, unlike generators.

How do I decide between using a generator and a list comprehension?

Choose a generator for large datasets or when memory is a concern, and use list comprehensions for smaller datasets where readability is key.
