In this lesson, you’ll see how to use
filter(). The built-in function
filter() is another classic functional construct and can be converted into a list comprehension.
It takes a predicate as a first argument and an iterable as a second argument. It builds an iterator containing all the elements of the initial collection that satisfies the predicate function.

This has been really useful for someone like me who is slowly making his way from novice to something like apprentice with aspirations for craftsman. I am curious about one very small bit: if the goal of lambda functions is to have things in one line, why not
above_avg = list(filter(lambda x : x > mean(nums), nums))?
