To find the largest items in a collection, heapq module has a function called nlargest, we pass it two arguments, the first one is the number of items that we want to retrieve, the second one is the collection name: import heapq numbers = [1, 4, 2, 100, 20, 50, 32, 200, 150, 8] print(heapq.nl...

The most interesting property of a heap is that its smallest element is always the first element: heap[0] import heapq numbers = [10, 4, 2, 100, 20, 50, 32, 200, 150, 8] heapq.heapify(numbers) print(numbers) # Output: [2, 4, 10, 100, 8, 50, 32, 200, 150, 20] heapq.heappop(numbers) # 2...

Options have a flatMap method. This means they can be used in a for comprehension. In this way we can lift regular functions to work on Options without having to redefine them. val firstOption: Option[Int] = Option(1) val secondOption: Option[Int] = Option(2) val myResult = for { firstValue ...
