What is the difference between map and filter in Python?

What is the difference between map and filter in Python?

The map function applies a given function to all items in an iterable, while filter creates a subset of items that satisfy a condition.

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

Sure! For map, you can use it like this: list(map(lambda x: x*2, [1, 2, 3])) which returns [2, 4, 6]. For filter, you can do: list(filter(lambda x: x > 1, [1, 2, 3])) which returns `[2, 3].

Are they both used with functions?

Yes, both map and filter take a function as their first argument. map applies the function to each item, while filter uses it to determine if an item should be included.

When should I use one over the other?

Use map when you want to transform data and filter when you want to select specific items based on a condition.
