How can I use map and filter functions in Python?

How can I use map and filter functions in Python?

You can use the map() function to apply a function to all items in an iterable, and filter() to filter items based on a condition.

Can you give me an example of using map?

Sure! For example, if you have a list of numbers and want to square them, you can use map() like this: squared = list(map(lambda x: x**2, numbers)).

What about filter? How does that work?

With filter(), you can filter out items that don't meet a condition. For instance, to get even numbers from a list, you can use: evens = list(filter(lambda x: x % 2 == 0, numbers)).

Can I combine map and filter?

Yes, you can! For example, you can first filter the list and then apply map(). Like this: result = list(map(lambda x: x**2, filter(lambda x: x % 2 == 0, numbers))).
