How can I improve the performance of my Python iterators?

How can I improve the performance of my Python iterators?

You can improve iterator performance by using generator expressions, avoiding unnecessary list conversions, and leveraging built-in functions.

What are generator expressions and how do they differ from regular functions?

Generator expressions are a concise way to create generators using a syntax similar to list comprehensions, but they yield items one at a time.

Can you give me an example of a generator expression?

Sure! Here's a simple example: squared_gen = (x**2 for x in range(10)) creates a generator that yields squares of numbers from 0 to 9.

How does using a generator improve memory efficiency?

Generators yield items one at a time and do not store the entire list in memory, which reduces memory usage significantly.
