In general,append()is the most efficient method for adding a single element to the end of a list.extend()is suitable for adding multiple elements from an iterable.insert()is the least efficient due to the need to shift elements to make space for the new element. The+operator creates a n...
In this step-by-step tutorial, you'll learn how Python's .append() works and how to use it for adding items to your list in place. You'll also learn how to code your own stacks and queues using .append() and .pop().
