Efficient for large datasets.
Quick Answer
Iterator: object with __iter__() and __next__() methods that produces values one at a time. Generator: function using yield that automatically becomes an iterator - pauses at each yield and resumes from there. Generators are lazy (compute on demand, memory efficient). Use generators for large sequences where computing all values upfront would be expensive. Generator expression: (x**2 for x in range(10)).
