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 both functions?

Sure! For example, if you have a list of numbers and you want to square them, you can use map() like this: squared = list(map(lambda x: x**2, numbers)). To filter out even numbers, you can use filter(): evens = list(filter(lambda x: x % 2 == 0, numbers)).

What if I want to combine both map and filter?

You can combine them by first filtering the list and then mapping the result. For example: result = list(map(lambda x: x**2, filter(lambda x: x % 2 == 0, numbers))).

Thanks! This is really helpful.
