How do different iterators compare in performance?

How do different iterators compare in performance?

The performance of iterators can vary based on their implementation. For example, in Python, list comprehensions are generally faster than using a for loop with an iterator.

What factors affect the performance of iterators?

Factors include the type of data structure, the complexity of operations performed during iteration, and whether the iterator is lazy or eager.

Can you give examples of different types of iterators?

Sure! Common types include simple iterators, generator expressions, and built-in functions like map() and filter().

Which iterator is the most efficient for large datasets?

For large datasets, generator expressions are often the most efficient as they yield items one at a time and use less memory.
