Quick Answer
Generators use lazy evaluation - values produced one at a time on demand, not all at once. Memory efficient: a generator for 1 million numbers uses constant memory vs a list using millions of bytes. Pipelines: chain generators to process data step-by-step (like Unix pipes). yield pauses execution and returns a value; next() resumes from where it left off. Use for large files, infinite sequences, data pipelines.
