How can I improve performance using Python iterators?

Using iterators in Python can significantly improve performance by reducing memory usage and allowing for lazy evaluation. Would you like to see some examples?

Yes, please show me an example of using iterators.

Sure! Instead of using a list, you can use a generator expression. For example, instead of sum([x*x for x in range(1000000)]), you can use sum(x*x for x in range(1000000)). This way, values are generated on-the-fly.

What are the benefits of using generators over lists?

Generators are more memory efficient because they yield items one at a time and do not store the entire list in memory. This is especially useful for large datasets.
