Iterables, Iterators, and Generators in Python

In Python, iterables, iterators, and generators provide methods for generating data collections and for ordered traversal of data. If the amount of data generated is relatively small, it is recommended to use iterables; if the amount of data generated is large, it is recommended to use iterators or generators. Since the implementation of generators is … Read more
