I do not advocate it. The range perform is helpful once you'd wish to loop over numbers. Python 2's range operate returned a listing, which means the expressions above would make very very large lists.

0 to verify whether each ingredient is even or odd. List comprehension is a concise solution to create a listing from an present checklist or different iterable sequence.
