How does the reduce function work in Python?

The reduce function in Python is used to apply a rolling computation to sequential pairs of values in a list.

Can you give me an example of how to use it?

Sure! Here's a simple example: from functools import reduce. Then you can use it like this: reduce(lambda x, y: x + y, [1, 2, 3, 4]) which sums up the list.

What if I want to use it for multiplication instead?

You can do that too! Just change the lambda function: reduce(lambda x, y: x * y, [1, 2, 3, 4]) will multiply all the numbers together.

Are there any alternatives to reduce?

Yes, you can use a simple for loop or list comprehensions for similar tasks, depending on your needs.
