Learn

In this lesson, we learned how to:

  • Add elements to a list by index using the .insert() method.
  • Remove elements from a list by index using the .pop() method.
  • Generate a list using the range() function.
  • Get the length of a list using the len() function.
  • Select portions of a list using slicing syntax.
  • Count the number of times that an element appears in a list using the .count() method.
  • Sort a list of items using either the .sort() method or sorted() function.

As you go through the exercises, feel free to use print() to see changes when not explicitly asked to do so.
