Summary
Explore the iterator pattern as a foundational design pattern in Python. Understand how iterators, comprehensions, and generator functions provide efficient ways to handle and transform data collections, enhancing your ability to write clean and effective code using Python's object-oriented features.
Recall
This chapter looked at a design pattern that seems ubiquitous in Python, the iterator. The Python iterator concept is a foundation of the language and is used widely. In this chapter we examined a number of aspects:
- Design patterns are good ideas we see repeated in software implementations, designs, and architectures. A good design pattern has a name, and a context where it’s usable.
