What are some efficient iteration techniques in Python?

In Python, you can use techniques like list comprehensions, generator expressions, and the built-in map() and filter() functions for efficient iteration.

Can you explain how list comprehensions improve performance?

List comprehensions are faster than traditional loops because they are optimized for performance and reduce the overhead of function calls.

What about using generators? How do they compare?

Generators are memory-efficient as they yield items one at a time, which is great for large datasets. They can be slower than list comprehensions for small datasets due to the overhead of function calls.

Are there any scenarios where traditional loops are better?

Yes, traditional loops can be more readable and easier to debug, especially for complex operations or when maintaining state across iterations.
