Adding items to a list is a fairly common task in Python, so the language provides a bunch of methods and operators that can help you out with this operation. One of those methods is .append(). With .append(), you can add items to the end of an existing list object. You can also use .append() in a for loop to populate lists programmatically.

In this course, you’ll learn how to:

  • Work with .append()
  • Populate lists using .append() and a for loop
  • Replace .append() with list comprehensions
  • Work with .append() in array.array() and collections.deque()
