What are some examples of map and reduce in programming?

Can you explain what map and reduce functions are in programming?

Sure! The map function applies a given function to each item in an iterable, while reduce combines items to produce a single result.

Can you give me a practical example of using map?

Absolutely! For instance, if you have a list of numbers and you want to square each number, you can use map like this: map(lambda x: x**2, [1, 2, 3, 4]).

And what about reduce? Can you show me an example?

Certainly! If you want to find the sum of a list of numbers, you can use reduce like this: from functools import reduce; reduce(lambda x, y: x + y, [1, 2, 3, 4]).

How do these functions improve code efficiency?

They enhance code efficiency by allowing you to process data in a more functional style, reducing the need for explicit loops.
