Generator expressions and pipelines

Chain small lazy stages into data pipelines with generator expressions and yield from, and see why they use so little memory.

You will be able to

• Write generator expressions and pass them directly to sum(), max(), any() and similar functions
• Build a pipeline of generator stages that each do one job
• Explain the order in which a lazy pipeline processes items and why it saves memory
• Delegate to another iterable or recursive generator with yield from
